plugin XEP-0384: fix trigger used for OLDMEMO:

OLDMEMO was applied at the `send_message_data` trigger level, however this was missing
stanza constructed without message data (which is notably the case for XEP-0308). This has
been fixed by using the `send` trigger instead. As a side effect, the same code is now
used for TWOMEMO and OLDMEMO, making it simpler.
