In PC integration tests, create tracks/streams with random IDs.

Previously the helper methods (like "CreateLocalAudioTrack") were using
hard-coded IDs. This means if you try to add two tracks to the same
PeerConnection you'll get an ID conflict. Tests were getting around
this by using APIs to explicitly add tracks with different IDs. But
this leaks an implementation detail of the helper methods, and is a
hassle.

So instead, just use random UUIDs from the helper methods. This is how
IDs are created in the real world, so it's pretty reasonable and allows
the tests to be made more readable.
