[bug] fixes for display attachments and move between folders

- Add errback handling to catch properly errors that were not allowing
  the complete insertion of the parts for a given message. Fixes blank
  attachments and moving of messages to different folders.
- Force overwritting of mdoc when it is a copy. This was avoiding a
  message to be copied back to a folder from where it already had been
  copied to another (since the mdoc was already existing there, with the
  same doc_id, which was forbidding the creation of the new one).
  This case also needs special care in the indexer, since we have to
  delete the old hash entry first.
