Fix ActionDispatch::PublicExceptions returning string rack status

The status returned in the rack [status, headers, body] array was
a string, which can cause problems with middleware that assumes the
status will be a Fixnum. This likely never surfaced because other
middleware to_i the status returned from downstream apps before
passing it on.
