VisibilityChecker: Use RefDatabase.getTipsWithSha1() for visibility check

The visibility check retrieves all refs, peels them and compares if
they point to the requested object. This is offered now in in the
RefDatabase.getTipsWithSha1() method. Using that method, we also
benefit from fine-tuned implementations for the specific storage in use.

Replace the loop with that method.
