Validate any spawned commit transaction prior adding them to the wallet #1050
Description
As has been described in the #996 (comment), node could keep invalid spawned finalizer commit transactions in the wallet because there's a lack of validation of them prior adding to the wallet.
This could be fixed in a similar way as #1040 does it for deposit transactions. @kostyantyn also came with a proposal to use ContextualCheck: #1040 (comment). 3rd option is to apply the full transaction validation path.
User-driven commits (definitely must be fixed):
- deposit Validate deposit prior adding to the wallet #1040
- logout
- withdraw
- admin
System-driven commits (needs more investigation):
- vote
- slash
