There should be a way to test overwriting pending transactions

See original GitHub issue

With the current functionality of Ganache Core, if you try to broadcast a transaction with a higher fee that has already been broadcast with the same nonce, you will receive the following error the tx doesn't have the correct nonce. account has nonce of: 1 tx has nonce of: 0.

This is because it verifies the nonce itself before running against the vm https://github.com/trufflesuite/ganache-core/blob/283cbeca1cf9f9c598845a00baaa331afc621596/lib/statemanager.js#L965

ganache-core does not currently support a mempool, although this WIP refactor by @davidmurdoch does support a mempool to some degree https://github.com/trufflesuite/ganache-core/blob/a4e8989efc301b28d094082297dfbb1c4b25a744/src/ledgers/ethereum/components/transaction-pool.ts#L80-L87

A feature like this is incredibly important for DApp developers. Especially ones creating time sensitive DApps that need to ensure parties can overwrite pending transactions.
