Apply application visibility checks during normal object filtering

Summary:
Fixes T9058. Normally, "Query" classes apply an application check and just don't load anything if it fails.

However, in some cases (like email recipient filtering) we run policy checks without having run a Query check first. In that case, one user (the actor) loads the object, then we filter it against other users (the recipeints).

Explicitly apply the application check during normal filtering.

Test Plan: Added a failing test case and made it pass.
