[Wallet] Ignore MarkConflict if block hash is not known #1767

Merged

Conversation

backports bitcoin#7491

If number of conflict confirms cannot be determined, this means that the block is still unknown or not yet part of the main chain, for example during a reindex. Do nothing in that case, instead of crash with an assertion.

Fixes bitcoin#7234.
