Closet wrapping fixes

- Fixes resisting out of closets that are wrapped or welded. Probably locked closets too. do_after() proc checks that the user is in the parent turf. This was failing since the user is in a locker, not the turf. Cut it out instead of touching do_after() since it's used by tons of other code, and we are doing sanity checks before running the rest of the code anyway.
- Removes the ability to wrap closets that you are inside.
