bpo-36348: IMAP4.logout() doesn't ignore exc (GH-12411)
The imap.IMAP4.logout() method no longer ignores silently arbitrary
exceptions.

Changes:

* The IMAP4.logout() method now expects a "BYE" untagged response,
  rather than relying on _check_bye() which raises a self.abort()
  exception.
* IMAP4.__exit__() now does nothing if the client already logged out.
* Add more debug info if test_logout() tests fail.
