- 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.
`selectMyActiveClaims` includes `byId`, which gets invalidated on each resolve. Having this as an input selector breaks memoization.
For the case of comment-filtering, we don't really care about pending or abandoned own claims (I think), so just grab the raw IDs.
* Prevent multiple parseURI calls
## Ticket
129
## Issue
Code was shortened to use `isURIValid` during the consolidation. `isURIValid` calls `normalizeURI`, which calls another `parseURI`.
`parseURI` is pretty expensive.
## Approach
- Add optional parameter to `isURIValid` to skip the normalization.
- Set those that were converted during the consolidation to skip the normalization. Also covered a few other instances where it is obvious to me that normalization is not required.
- For the rest, I can't tell for sure if it's safe to remove the normalization, so the default `normalize=true` will leave things as is.
The whole `parseURI` probably needs a refactoring, or a few lighter version for specific needs.
* Simplify isURIEqual
## Issue
`parseURI` is too expensive to be used in a loop, plus `normalizeURI` itself is calling `parseURI`.
## Approach
Not sure if it covers all cases, but just try convert colons to hashes before comparing.

- Moved the filtering to the reducer side, so that we don't do it every time. We can't rely on `createSelector` because the store will be invalidated on each `USER_STATE_POPULATE`, unfortunately.

- Memoize via re-reselect for the "ForUri" selector.
## Issue
`makeSelectDataForUri` always returns a new reference, so `ClaimPreview` was constantly being rendered. It's pretty expensive since `ClaimPreview`'s rendering checks against a huge blocklist, which is another issue on it's own.
## Changes
- This commit tests the usage of `re-reselect` as the solution to the multi-instance memoization problem (https://github.com/toomuchdesign/re-reselect/blob/master/examples/1-join-selectors.md)
