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.

To change Icon not to use PackageManager.getResourcesForApplicationAsUser
lets StatusBarIconViewTest no need to mock
getResourcesForApplicationAsUser in mock PackageManager instance.
