Don't you want to push url_ to the edit_?

I do this in OnEmbed() because the textfield doesn't exist yet. None of the
views stuff can be initialized until AuraInit is instantiated. That can't happen
in the ctor because the ctor is run before the command line is initialized. I
really need to restructure this class into a couple.

+  app_impl_->ConnectToService("mojo:window_manager", &window_manager);
+  window_manager->Embed("mojo:omnibox", nullptr, nullptr);
