JITSI: catch all exceptions that occur on CaptureSession creation

For some devices the captureFormat is never initialized,so captureFormat.width throws NPE.
Fatal Exception: java.lang.NullPointerException
Attempt to read from field 'int org.webrtc.CameraEnumerationAndroid$CaptureFormat.width' on a null object reference
