Ask for the unread count, not the whole folder tree

The mail badge needs one integer and was fetching every folder in the mailbox to find it, which on the IMAP providers is the most expensive call the mail backend makes. EmailService now exposes the single-folder unread count that MailReader has always been able to answer with one STATUS. This is the fallback the badge uses when its unread socket has failed or gone quiet, so it was at its most expensive exactly when something was already wrong.
