Removing Packs from a world is still not saved properly if you click Play

This is related to MCPE-239834.

That bug is mostly fixed, but if you in the Edit World menu remove a resource pack that is a part of an Add-On that is connected to a behavior pack, and then press Play instead of exiting, that pack is still going to load in the world.

Steps to reproduce:

1. Open the Edit World menu for a world that has an Add-on already enabled.

2. Remove that Add-on’s resource pack in the Resource Packs tab. Then click Just Continue if a pop-up shows up.

3. Click Play.

Expected result:

After you enter the world, the pack you removed wouldn’t be in the world.

Actual result:

The pack you removed is still part of the world.
