mempool: don't log error when trying to remove a tx that's not present #651
Description
Using the new mempool, during the genesis startup of a chain, you will see an error being logged for each gentx you have:
3:14PM ERR failed to remove Cosmos transaction error="tx not found in mempool" module=ExperimentalEVMMempool
as these special transactions were clearly never be added to the mempool.
I think it is safe to ignore errors when a transaction was tried to be removed from the mempool but it wasn't found at all. Cosmos SDK is doing the same here:
When you start having more and more gentxs, it can be a bit alarming to see a wall of errors 😁
