Cherrypick some performance code - some manual work.

Frequently used; top in perf profile

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.
