Re: [webrtc-pc] examples: dont fiddle with srcObject if already set

Created #1135 for the above issue.

Can we mention in a comment somewhere why the `!srcObject` check is needed? Which I'd assume is to avoid invoking the [media element load algorithm](https://www.w3.org/TR/2015/WD-html51-20150506/semantics.html#media-element-load-algorithm) twice.
