Fixes ordering on AppsFilter#removePackage

Package remove was updating the forceQueryable state entirely too late
in the removePackage method (before re-adding shared user packages still
on device), resulting in the forceQueryable state being removed
incorrectly. I've restructured the method to do all operations before
adding shared user packages and the cache.
