Performing a gst_sdp_media_get_caps_from_media() would result in changing fields in the GstSDPMedia violating the const tag in the function declaration. Before there would be a line with a=rtpmap:96 VP8/90000 after, that attribute would only contain a=rtpmap:96 Fix by performing modifications on duplicated strings instead of on the internal values. Also add a simple test for checking that the representation doesn't change by a gst_sdp_media_get_caps_from_media()
