Enable mock capture devices on the iOS simulator

• Component: WebRTC
• Status: RESOLVED FIXED

[Karthik]

Testing webRTC or making webRTC calls on iphone/ipad emulator is not possible at the moment. 
We assume it is because there are no media devices enumerated.

The solution for this will be enabling the fake media source on the emulators so that webRTC calls can be placed.
