Reproduction Steps

1. Load a non-lifterlms related admin page (ie. page for another plugin)
2. See if lifterlms/assets/js/llms-admin-media-protection-block-protect.js or lifterlms/assets/vendor/select2/js/select2.min.js are loaded

Expected Behavior

Script is not loaded

Actual Behavior

Script is loaded

This can cause an increase in conflicts with select2 (ie. with Booking Activities > Calendar Editor).
