Sending future nonce transaction in eager mode causes Ganache to hang

[MicaiahReid]

If a transaction is sent with a future nonce while in eager mining mode, Ganache hangs indefinitely and never returns a response for the transaction.

This happens the blockchain's queueTransaction function. A future nonce transaction will return false for isExecutable, yet the code path still leads to awaiting transaction.once("finalized"), which won't happen until the nonce gap is filled.

Does this PR resolve #2509 as well?

Even worse, Metamask hangs as well and never comes back, just showing the spinner ...

Do we finally have a solution for this? I'm still having it.

It isn't hanging. When future-nonce transactions that are sent to Ganache running in eager mining mode appear to hang indefinitely, rather than being mined or rejected. This is expected behavior in eager mode, as Ganache does not return the hash until after it is mined. To help alleviate the confusion we now log a message about the status of these kinds of transactions.
