Move marked mistake in server analysis is top engine move

Exact URL of where the bug happened

https://lichess.org/JaGtAWXP/black#60

lichess marks this move as a mistake and writes "lost forced checkmate sequence" when in fact it's the top engine move and still leads to forced mate in 7.

I think this could be improved by overwriting the server analysis with local analysis if the local analysis is deeper.

Steps to reproduce the bug

go to the url above and look at moves 59/60, which are marked a mistake for black

What did you expect to happen?

move not marked mistake

What happened instead?

move marked mistake
