Refactoring DevTools bridge tests: moving interface adapters to SignalingReceiverProxy. 

Benefits of this refactoring are:
1. Removed a redundant adapter.
2. Removed an unnecessary interface conversion (A->B->A).
3. Removed from ClientSessionTestingHost references to unrelated class LocalSessionBridge.
4. Reduced number of public classes.
