fix: correctly apply genesis

[klkvr]

Motivation

Closes #4173

Caching genesis accounts state is not really correct because we might reset fork to a forked block where account nonce is lower than the one we cached and inserted during reset. This would cause eth_getTransactionCount to return nonce lower than the one actually stored in the db

Solution

This PR removes caching of genesis accounts state, which makes anvil_reset a bit slower

Another approach could be to instead serve overriden data over getTransactionCound/getBalance etc, but I don't think that it's great to mess with the actual forked state

ah very nice

we can live with the overhead on reset
