Android: handle move operation with content uris

Allow moving content uris if the destination is provided
a full content uri with a parent that's different from the
source content uri (i.e. different folders).

Note: since the underlaying Android APIs don't always know about
the parent of a uri, we do some step to deduce that, but that's
not always guaranteed to work.
