## Interesting
Uploads Page uses `claim_list`
Channel Page uses `claim_search
A second `claim_list` would instantly show updated results, but `claim_search` takes a long while to reflect the deletion.
## Change
This PR only handles the `claim_list` (Uploads Page).
The `claim_search` version would be troublesome to handle. If a refresh would bring back the results (due to the `claim_search` slow update behavior), we would need to store the deleted claim persistently. Then ...
- Store where? rehydrate?
- When to clear?
- How to make each `ClaimList` filter this out without polluting the code? etc.
...will be messy. Feels easier to "fix" at the `claim_search` level to make it update faster (maybe a command to clear cache at server or something).

## Issue
If you are already at the homepage and you click the "Home" or "Odysee" logo again, the entire page reloads, causing the whole startup sequence to re-run (lots of fetches).
This can be annoying when not intended (e.g. clicked too many times), as startup is slow for some and we also lose non-persistent Redux data (for debugging).
I believe the requirement was just to reload the homepage tiles, as they might be showing stale ones after a while. A full reload was the quick-and-easy fix.
## Approach
Best not to touch the complicated `ClaimTilesDiscover`, so just clear the search cache key in this scenario. `ClaimTilesDiscover` will then pick this up and perform a new `claim_search`.
## Issue
- selectMyActiveClaims memo problem -- being recalculated on every click -- high workload for wallet with large uploads.
- Mistake in handling abandoning IDs (it was trying to extract keys from an array)
## Changes
- selectAbandoningIds: never use `state` as an input selector. Breaks memo.
- Don't use selectMyClaimsRaw and then reduce it back to IDs. Use selectMyClaimIdsRaw instead.
- selectAbandoningIds is already in array form, so don't run Object.keys.
- Fix abandoningById never clearing when succeeded.
* Don't update 'pendingById' if no changes.
'pendingById' isn't frequently updated, but using it as a proof-of-concept to fix how reducers should be written to avoid unnecessary updates.
ImmutableJS apparently does all of this for us, but there are cons to using it as well, so using own wrappers for now.
* Don't update 'byId' if no changes + add 'selectClaimWithId'
## Ticket
116 Claim store optimization ideas (reducing unnecessary renders)
## Changes
- Ignore things like `confirmations` so that already-fetched claims aren't invalidated and causes re-rendering. The `stringify` might look expensive, but the amount of avoided re-renders outweighs it. There might be faster ways to compare, though.
- With `byId[claimId]` references more stable now, memoized selectors can now use 'selectClaimWithId' to pick a specific claim to depend on, instead of 'byId' which changes on every update.
* Fix memo: selectMyChannelClaims, selectActiveChannelClaim
## Issue
These should never recalculate after `channel_list` has been fetched, but they do because of poor selector dependency.
## Change
With the `byId` changes from the previous commit, we are now able to memoize these selectors correctly.
