Closes 916 "NaN in Total Staked Amount"
Contemplated putting the fallback into `<CreditAmount>` itself, but decided to minimize testing. Not sure if there are clients that would rely on NaN being used.
## Why
Frequently used; top in perf profile
## Changes
Most of the time, you already have the claim object in the current context. `selectClaimIsMineForUri` will retrieve the claim again, which is wasteful, even if it is memoized (looking up the cache still takes time).
Break apart the logic and added the alternative `selectClaimIsMine` for faster lookup.
## 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.
