## Issue
`normalizeUri` | `parseURI` is expensive and has been causing sluggish operations when called repeatedly or within a loop.
## Change
Since I'm not confident enough to remove the call entirely from makeSelectClaimIsMine (although I've yet to find a scenario that the uri is not already normalized), we'll try caching the calls instead.
## Results
- in a simple test of toggling between 2 category pages, we saved 20ms from `parseURI` calls alone.
- in a test of opening all categories one time, the memory usage remained similar. This makes sense since we removed a `makeSelect*` (which creates a selector for each call + not memoizing), and replaced that with a cached selector that's actually memoizing.
- selectMyChannelClaims depends on `byId`, which currently is always invalidated per update, so it is not memoized.
- Most of the use-cases just needs the ID or the length of the array anyways, so avoid generating a Claim array (in selectMyChannelClaims) unnecessarily -- the client need to reduce it back down to IDs again :/
- The simpler boolean also removes the need to memoize the selector, which saves a bit of memory.

## Issue
- Infinite `resolve` loop when deleted channel is present in the comments.
- Since it was only displayed comments with resolved channels, it masked away those comments. While that may or may not be regarded as a defect, I think we should do it at Commentron instead of at the app if we want to filter deleted channels. I vote to show comments from deleted channels, since it might have good conversation thread.
Previously, we decide when to display "Show More" based on the current fetched reply count vs. total replies in Commentron. It was already troublesome as `comment.List` and `comment.replies` give different values (one includes blocked content, while another does not).
Now, we are further filtering the list with Commentron blocklists (personal, admin, moderator), so it is not feasible to run the logic based on reply count.
## Solution
- Keep track of number of remaining pages instead and use that to determine when to display "Show More".
- While it doesn't solve the "Show N replies" mismatch (YT has this problem too), it prevents the button from lingering.
- In the event that all replies are blocked, just show an empty space (same as YT). I didn't like the previous version that cluttered the space with "comment(s) blocked".
## Issue
- `Comment.replies` currently represent all replies, while `comment.List` returns a filtered version, so the actual replies could be less.
- The actual replies is represented by `total_filtered_items`, but we only get that after making a fetch. So, users could click "Show more" but get nothing.
## Fix
- Stop showing "Show more" based on `total_filtered_items`.
- If there is a balance, display 1 dummy comment to represent all blocked replies. This handles the case of "Show more" being displayed but ended up with 0 replies if all replies were blocked.
## Future
Note that `Comment.replies` might be changed to represented filtered comments in the near future (refer to Beamer), so the GUI is made such that the dummy just won't appear when that change happens.
