Summary: Fixes T2698. When applications are installed, their Conduit calls should drop out. This will also let us land Releeph without exposing Conduit calls.
Test Plan:
- Viewed Conduit console; uninstalled some applications and verified their calls dropped out.
- Tried to make an uninstalled call; got an appropriate error.
