[Partial screensharing] Fix crash when having a recents app available only in work profile
AppIconLoader in the recent app selector crashed when getting
information about an app that is available only in work profile.
This is because package manager gets activity information only
for the current user.
Replaced with using private package manager wrapper that allows
to get activity info for any user.

Test: open app selector with work profile apps in the recents
