SCI: QfG3 - Moonwalking and a stunned Laibon when a Thief casts Open while sneaking

[lwcorp]

3 issues for the price of one:
1) When a Thief sneaks into the Laibon's hut and casts Open on the storage chest, he does a moonwalk. The chief then wakes up, looks at the thief...and couldn't care less, so the thief can still steal whatever he wants and walk out.
2) If the Thief then looks at the chief, it describes Uhura (should she be offended?). If you talk to him, he's addressed as "they" and it's claimed "they" suddenly don't speak English.
3) If the Thief oils the chest first, then it displays <Messager> 450: 7, 75, 74, 1 not found, but it's harmless and clicking on it just goes back to the first 2 issues.

Tried in daily ScummVM 2.7.0git1742-g25496c5a84e (Jul 30 2022 04:02:53).
And stable ScummVM 2.6.1pre10-g52fcb0da8d7 (Jul 29 2022 04:48:19) as requested in ​https://www.scummvm.org/news/20220605/

P.S.
The Leopardman Chief's house has a similar sneaking scene, but casting Open there causes no errors, just kills the Thief when he tries to steal from the opened chest.
