msgstore_fs: fix direct message targets

Browse source 
When fetching messages via draft/chathistory from a conversation
with another user, soju would send the following:

    :sender PRIVMSG sender :hey

instead of

    :sender PRIVMSG recipient :hey

because the file-system message store format doesn't contain the
original PRIVMSG target.

Fix this by doing some guesswork.
