upgrade mainnet forking tool to support provider endblocker changes

[MSalopek]

Tool stopped working on versions >= v20.0.0.

 gaiad testnet unsafe-start-local-validator  \
--validator-operator="cosmosvaloper1pazy2th7lz38pjlxgt6d72p82trkdlrqnh3ja7"  \

--accounts-to-fund="cosmos1pazy2th7lz38pjlxgt6d72p82trkdlrqkr983d"

Seems related to cometbft v0.38.11 and higher versions.

The tool encounters a consensus failure with node snapshots:

The problem was in provider's store, since we didn't clear the data related to the old validator set. Fixed with #3375
