Remove triggerable unhandled exceptions from blacklist code

[cxmplex]

Please note you should reevaluate your blacklist function as well, I have not checked for other methods such as missing minimum stake checks, allowing unregistered checks, etc.

For instance, an exception is still possible to be thrown if the miner sets self.config.blacklist.allow_non_registered. Why a miner would do this when not on testnet, who knows.

Not using blacklist as miners are scored only on commit data, no axon/dendrite activity in this subnet
