Remove PackageManager.getResourcesForApplicationAsUser API

To switch another user to do something should create the context of the
specified user by using Context.createContextAsUser rather than call
*AsUser API directly.

Replacing PackageManager.getResourcesForApplicationAsUser with
context.createContextAsUser(...) applys in not only ShortcutService
but also the related ShortcutManager test.
