IDX Profile Cache Logic

[zachferland]

Continue to hit cache for 3box profile (and write to cache once resolve).

When we resolve a ceramic profile dont write it to cache following the request, and delete 3box profile from cache. Currently the cache is keyed by orbit db address.

Actually believe this is not needed now. Caching at different level than i remembered (orbitdbaddress). But keeping story to just double check and make sure that current logic will still make sense. Should still be part of test ideally.
