lilia 8453424ebd Fix stuck pending messages state
Refactor outgoing message error handling to use the same success and
error handlers. This creates a somewhat strange pattern, where we call
send and pass in the promise that resolves when sending is complete, but
there's enough variety in the libtextsecure syntax for different message
sending routines that it belongs at the conversation level and only the
post-processing stuff is really shared by all messages.
