Fixes paper making bodybags inescapable (#95248)

## About The Pull Request

passes `user` in the `open()` for when someone attempts to leave an
unlocked, unwelded container such as a bodyag. The reason for the bug
was attempting to give a null user the pinned piece of paper.

Also adds an exception for no user being passed into `open()` for the
sake of revenant's defile & likely other things in the future.

Also fixes an unrelated bug where the reason that taking off the pinned
paper from a bodybag would stop it opening was a runtime rather than
returning false. Behaviour remains identical.

## Why It's Good For The Game
