Loosen imap_open_mailbox() SELECT response data parsing.

DavMail is putting more than one space between '*' and the EXISTS
count, e.g. '*  5 EXISTS'

Strictly speaking, this is disallowed by RFC3501 (see Section 9, Note
2).  However, there is also no good reason for imap_open_mailbox() to
be stricter than the untagged handler, which correctly extracts the
count.

Add a check to make sure we are looking at an untagged response, and
then use imap_next_word() rather than just incrementing by two.

Thank you to Michael Gernoth (@stargo) for debugging this issue,
creating a merge request with a possible fix, and helping to test this
commit.
