Subject: [PATCH] fix(imap): parse STATUS responses with an unquoted mailbox
 name

StatusParser required the mailbox name to be double-quoted
(`STATUS "INBOX" (...)`). RFC 3501 allows the name to be sent as an atom,
and Dovecot does so (`STATUS INBOX (...)`), so the regex never matched
and MESSAGES/UNSEEN/UIDNEXT were silently left at 0 for every mailbox.

The regex now accepts either a quoted string or an atom.
