fix foldable clothes not working while worn

About the PR

Fixes a bug where foldable clothing cannot be toggled when worn by a player.

Technical details

Previous changes to this code introduced a strange regression. The UnfoldedHideLayers and FoldedHideLayers were made nullable so that the default null value could be used to check for nothing being there and certain buggy interactions could be blocked.

The issue, however, is that the component's default value is an empty hashset, which is not null. Despite this not causing the buggy behavior being guarded against, it was still getting blocked, preventing any foldable clothing from being folded while worn.

To fix this, we simply make the hashset non-nullable and use the empty list to check rather than a null value.

Tested in-game, appears to work

Prior to this, the labcoat would display the same message as the bandana and not unfold.
