imap: Fixed assert-crash if client disconnected at a specific command state.

If there was a command with state=CLIENT_COMMAND_STATE_WAIT_SYNC and output
stream was already detected to be closed, we crashed with:

Panic: file imap-client.c: line 841 (client_check_command_hangs): assertion
failed: (!have_wait_unfinished || unfinished_count > 0)
