Includes both direct boot aware and unaware apps in Apps default view

The view should be showing a combined list of "downloaded"
+ "visible in launcher" apps. However, if FBE and work callenge are
enabled, after a reboot the direct boot unaware apps are filtered.

Reason is that PackageUserState#isMatch assumes at least one of the flags
are specified and expects system to derive the aware/unaware flags
according to the user's lock state if neither of them is specified.
