Don't use the PM flag to reach across users.
If retrieving labels, etc., use MATCH_ANY_USER, since
several Settings screens show work profile apps as well.

Test: Manual test of affected screens

This CL extracts the code that counts the number of installed apps
for a set of users from ManageApplications to a helper class,
InstalledAppCounter. The new helper is designed to be unit-testable
(PackageManager dependencies are injected via a new PackageManagerWrapper
abstraction) and customizable (the set of users for which to count is
specified by subclasses).
The CL adds a unit test for the InstalledAppCounter as well.
Test: make RunSettingsRoboTests

Since it grabs a lock that can be slow on the main thread, don't use
ApplicationsState in any of the summaries, instead load the information
directly from the PM.
