Fix wrong detection for inbox folder

The function detectMailboxes() try explicitly excludes all folder names that are
not inbox, but forget to exclude "Delete" or "Deleted Messages" folder. Outlook
and some other mailboxes have this folder. Without this patch, "Delete" folder
will be set incorrectly as inbox and spoolfile.
