Updating the monkey to use a dedicated UI test bridge.

Browse Source 
1. The MonkeySourceNetworkViews was registering a raw event
   listener for accessibility events and hence perform
   connection and cache management in similar way to an
   AccessibilityService. This is fragile and requires
   the Monkey implementor to know internal framework
   stuff. Now the functionality required by the class
   is accessed via the new UiTestAutomationBridge.
