Do not launch floating window when on default launcher

We only do this when user is on the default launcher 
because if the user was on a non-default launcher,
he/she must have been there for some purpose and we 
do not want to throw him/her back to the default 
launcher incase he/she exits the app with HOME button.
Themes: Update LoadedApk resources.

Instead of creating a new LoadedApk when resources are not up to
date, we use the existing LoadedApk but recreate mResources.
