As muttrc provides a shortcut 'o' for syncing inbox folders, different mailboxes
may not have the same folder name, we should overridden this command in each
account's muttrc file.

Otherwise, a mailbox which has 'INBOX' as its inbox folder will see this error:

ERROR: Account qq: no folder to sync (folderfilter issue?)
 *** Finished account 'qq' in 0:06
ERROR: Exceptions occurred during the run!
ERROR: Account qq: no folder to sync (folderfilter issue?)

This patch fix this problem.

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.
