chore: convince dumpView and TestComponentRenderer to agree on things

 - all the TestBed tests except for the DetachedLoader ones and a single Renderer lifecycle are passing.
 - update NativeScriptRenderer.selectRootElement to find views by ID when given a selector of an id string. TestBed uses this when creating componentRefs to get at the correct views.
 - change NativeScriptTestComponentRenderer to inject only a ProxyViewContainer which mimics what TestApp did.
 - update dumpView to strip off the new "source" data attached to a view.toString() result.
