Title:
  Daemon fails to start up when processing removable media if there are
  duplicate keys in media and media_attic tables

Bug description:
  From a report from Mitchell Reese on the ubuntu-phone list, it seems
  we can hit terminate on startup when processing removable media.

  The log extract was:

      Mediascanner service starting at 2015-10-02  6:31:12.

      terminate called after throwing an instance of 'std::runtime_error'
        what():  UNIQUE constraint failed: media_attic.id

  This is almost definitely from the MediaStorePrivate::archiveItems()
  method, indicating that some of the items being moved to the attic
  were assigned the same primary key ID as other items we'd previously
  moved to the attic.

  Ignoring the ID field when copying between the two tables would
  probably be the best solution.

  As a work around for anyone who encounters this before we roll out a
  fix, deleting the media index should make the problem go away:

      stop mediascanner-2.0
      rm ~/.cache/mediascanner-2.0/mediastore.db
      start mediascanner-2.0
