Move many old HTTP test cases to the rest_handler test suite

A bug was fixed in cowboy_rest where when content_types_provided
returned a media type with a wildcard as first in the list, and
a request comes in without an accept header, then the media_type
value in the Req object would contain '*' instead of [] for the
parameters.
