First time, the constraints for createOffer is 
{
  'mandatory' : {
    'OfferToReceiveAudio' : true,
    'OfferToReceiveVideo' : false
  }
}.
Offer created has only audio media description (m=audio...).

Second time, the constrainsts for createOffer is
{
  'mandatory' : {
    'OfferToReceiveAudio' : true,
    'OfferToReceiveVideo' : true
  }
}.
Video media description (m=video...) is expected to be included in the offer created, but it isn't.

We don't support renegotation yet (we'll link the bugs to this).  I'm turning this into a bug on "I want to add (or remove) video from an existing call", since that's what the testcase was.

Note that this doesn't require *full* renegotation to be available - just enough for this usecase.

we support renegotiation now
