Expose `mailbox_for` method

Currently, the only exposed entry point into the ApplicationMailbox's configured
routing system is to call `route`, which performs a lot of work to fully
`process` inbound email. It'd be nice to have a way (e.g. in test) of checking
which mailbox an email would route to without necessarily processing it yet.
