Tests: fixed mail_imap_ssl.t too long shutdown.
Prior to literals support in IMAP test backend (e7f0b4ca0a1a), early backend
response was treated as invalid, with subsequent proxy connection close.
Now that the connection continues successfully, this requires connection
close before nginx shutdown. Otherwise, it would wait for proxy_timeout.
