Fix issue #2643754: Launcher is caching widget layouts for too long

With the .apk file names now changing during an update, we need
to make sure to flush all caches related to a package when the
package is removed.  Otherwise we can continue to use the old
package, since its old file may still exist if we try to load it
too soon.
