        Fixed <rdar://problem/4040321> Exception: Someone's trying to encode a WebDataRequestParameters instance

        Reviewed by Darin.

        If a delegate returns a mutated applewebdata: request in it's willSendRequest:
        method, we don't load using the WebDataRequest.  Instead we do a normal load.
        Unfortunately, if the request they return is mutated *copy* of the applewebdata:
        request it will hold the applewebdata: special properties.  These properties
        will be encoded into the cache.   They should not be.  So, to fix, we sanitize the
        request, by removing the special properties from the request.

        Note that we had to dig into the private guts of NSURLRequest because there is
        no public mechanism to remove properties from a request, see 4046775.
