fix: missing cred proof grouping

[wadeking98]

Summary of Changes

Previously if a credential was missing from a proof request, it wouldn't be displayed properly in the proof request screen, predicates and attributes would be split so that it appears that they're coming from two different credentials. I've added functionality to properly group missing credentials. Additionally I fixed some UI bugs that present themselves when all credenbtials in a proof don't exist in the wallet
