Revert "Send broadcast when package is 'about' to be removed"

This reverts commit 238e80a5c7edcb922ce15feebec74ea2475c31cb.
This was a band-aid that is being fixed in a future commit.

Change-Id: I89a928e2fd9cff2b1992a6e85eb5c96c5b8b9b0e
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.
