multisig: fix #8537 seed restore (suggestions by @UkoeHB)
- spend secret key is no longer the sum of multisig key shares;
no need to check that is the case upon restore.
- restoring a multisig wallet from multisig info means that the
wallet must have already completed all setup rounds. Upon restore,
set the number of rounds completed accordingly.
