Sync PK member profile on first message

First time a PK member sends a message in the channel, Discord sends a
MESSAGE_UPDATE with the proper avatar data for them. OOYE's speedbump
means sending this message will actually take the edit message path.
The edit message path previously did not force a profile sync. This is
why the Matrix profile did always show up after their second message,
because that message was not updated and took the send path.
