Finished added unit tests for dev_funds. These are weak tests as the FakeIpcProvider does not provide enough support for keeping track of accounts and balances and instead we are injecting the provider responses in the tests, which kind of defeats the purposes of the tests. Instead, the FakeIpcProvider should be a little smarter and do more of what a real node would do.
Clean up debugging statements from fund_accounts.
Removed the addition of the nonce increment for contracts deploy as this was only affecting mneumonic-generated accounts which is not meant for dev environment.
Now funds accounts only if they have not been funded, and also funds with only the amount needed.
Also fixed bug with unlocking accounts when re-running `unlockAccounts` on already created accounts.
