  imap-hibernate: Fix "DONE" handling.

1. If only "DONE\r\n" was sent, it randomly failed with BAD because of
out-of-bounds buffer read.

2. If "DONE\r\n" was followed by a command tag but no space afterwards, we
kept waiting for the input to continue. But since the DONE was already sent,
we should break the IDLE already at that point without any further waiting.

  director: Fix shutdown_clients=no to not break

The director process must shut down even with with shutdown_clients=no.
Otherwise the two director processes will try to keep competing with each
others and log errors like:

director: Warning: Director 10.0.0.123:9090/right disconnected us with reason: Replacing with new incoming connection
director: Warning: Director 10.0.0.123:9090/right disconnected us with reason: Replacing with 10.0.0.124:9090
