ira b0bd8722f3 Fix unsound EntityMut::remove_children. Add EntityMut::world_scope (#6464) ... `EntityMut::remove_children` does not call `self.update_location()` which is unsound. Verified by adding the following assertion, which fails when running the tests. ```rust let before = self.location(); self.update_location(); assert_eq!(before, self.location()); ``` I also removed incorrect messages like "parent entity is not modified" and the unhelpful "Inserting a bundle in the children entities may change the parent entity's location if they were of the same archetype" which might lead people to think that's the *only* thing that can change the entity's location. # Changelog Added `EntityMut::world_scope`.
