ART: Fix typo in ArtMethod::FindCatchBlock

The thrown exception is always resolved, as we have an instance of
it. What is potentially not resolved is the catch handler's exception
type.

The resolution failure will trigger a NoClassDefFoundError, which
should replace the original exception. For this, the API has to be
changed a little bit to tell callers that there was this change.
