[2.0.15] Locked space platforms sometimes show add platform button

[DeadMG]

What did you do?
I made a space platform, and then used /c game.player.force.lock_space_platforms()

What happened?
The add platform button remained available.

What did you expect to happen instead? It might be obvious to you, but do it anyway!
The add platform button should always be hidden if space platforms are locked, even if there's platforms present.

Does it happen always, once, or sometimes?
It seems to happen whenever the player has a platform or during platform undeletion- in other words, the "add platform" button is only hidden if there's no other platform UI to show, rather than always being hidden regardless.

See attached save, then run the command.
