AnonCreds RS should take predicates into account when querying credentials for a request

[TimoGlastra]

I think it will currently return e.g. a credential where age = 18 even if the predicate is age >= 21.

I couldn't find code that correctly does a post filter on the found credentials. @genaris is that correct?

Yes, I'm afraid the post filtering for predicates in holder service has not been implemented yet.
