Adds appropriate filtering for instant apps

Adds a new filter that includes downloaded and launcher apps, as well
as instant apps, and ensured that instant apps do not appear where
they previously were not expected (downloaded and launcher apps).

Test: Added testing for the existing filter and the new one.
