Clear search widget animation in Launcher.onResume()

Before, Launcher relied on a callback to a SearchManager.OnCancelListener to clear the search widget
animation. However, that doesn't get called if some other app opens the search dialog
before the Launcher is reopened. This change clears the animation in onResume().

Should fix http://b/issue?id=2246760
