The code that decides the apply action missed to handle non-transactional
messages and we didn't catch it in our testing as currently such messages
are simply ignored by the apply worker. This was introduced by changes in
commit 216a784829.
While testing this, I noticed that we forgot to reset stream_xid after
processing the stream stop message which could also result in the wrong
apply action after the fix for non-transactional messages.
In passing, change assert to elog for unexpected apply action in some of
the routines so as to catch the problems in the production environment, if
any.
