Bug 1444166 [wpt PR 9931] - Add used body replacement test for Reques…

…t constructor, a=testonly

Automatic update from web-platform-testsFetch: add used body replacement test for Request constructor

See Fetch change whatwg/fetch#675.

Specifically, that PR allows Requests with disturbed bodies to be used as the first parameter to the Request constructor, as long as the RequestInit dictionary contains a body member with which to replace the used body.

As of this writing, no browser implements this change.
