infinite-persistence ece2312ec5 selectClaimIsMineForUri to replace makeSelectClaimIsMine
## 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.
