Including UrlFor in Redirecting and Head will warn usefully if a controller is wired up without a router included (and still support redirect_to "omg")

Remove traces of SharedTestRoutes from user code; leave it as a standin for Rails.application.routes in Rails internal tests

fixed a 'RecordNotFound' bug when calling 'reload' on a object which doesn't met the default_scope conditions, added test [#3166 status:resolved]

The reload method didn't made use of 'with_exclusive_scope' when reloading the object. This lead to a RecordNotFound exception, in case the object doesn't met the default_scope condition (anymore) - which is obviously a bug. This quick fix makes use of with_exclusive_scope in the reload method as well. See test for full example.
