Crash when using invite code that's already been used up

[cinnamon-bun]

What's the problem you want solved?

If you use an invite code which has no remaining uses left, Oasis renders a white screen with a traceback

Error: non-error thrown: {"message":"invite not accepted",

Is there a solution you'd like to recommend?

Show a friendly error, "Sorry, that invite code has already been used"
