Summary [GStreamer] Playback rate is not set when pipeline is not ready.

When pipeline is not in paused or playing state, setRate method just return instead of postphoning requested rate. Also HTMLMediaElement is not notified about changed rate when: 1. there is error, 2. player is not able to change playback rate. Already working on patch. Will be proposed soon.

Comment on attachment 220827 [details] Patch This looks fine to me, but I know very little about GStreamer so I would prefer if someone who does (pnormand?) gives it an r+
