Return true only if the userManager belongs to private profile

The existing code asks the main user's userManager if there's a
private profile belonging to it. If a private profile exists then the
answer to that question will always be true. So, we always end up
showing the apps from the private profile for the personal case.

We should instead ask the userManager if it belongs to the private
profile or not.
