causes a 500 instead of a 400

------------------------------------------+------------------------
It looks like when `AdminEmailHandler` is configured with include_html a
`DisallowedHost` causes a 500 instead of a 400 because it is trying to
render the HTML error page for that to include in the email, but trying to
render that HTML is triggering its own `DisallowedHost` because it thinks
it is being requested by the same disallowed host rather than ignoring it
since it is rendering for an email.
