Make resources get package updates for all users

Previously when resources registered its package monitor for package
updates it wasn't passing a UserHandle so it was only getting updates
for the system user. This has caused various RRO issues when apps were
installed or updated. With this change we request updates for all users
which fixes some of the major issues we have seen.
