Unable to Send Transaction when selecting Tx Fee rates in MetaMask on v6

[tmashuang]

Repro Steps:

1. Be on any network with 2 created accounts with a balance
2. Send Button
3. Set Recipient Address to Account 2
4. Set Amount to 1 ETH (or any amount that is sufficient)
5. Set Slow or Fast Transaction Fee.
6. Insufficient Funds error on Amount.

Additional Context

In my send state, I believe it shows the correct amounts for gasPrice/Amount, but when I select Advanced Options it shows me 1000000000 GWEI.

Edit: No, the gas price is definitely not correct conversion to 1000000000 GWEI. Seems like we changed how to converted the Slow/Fast Tx Fee tabs to number, or vise versa.

@tmashuang perhaps from #6090 ?

[tmashuang]

We're adding a couple extra zeros here

metamask-extension/ui/app/components/send/send-content/send-gas-row/send-gas-row.container.js

Lines 82 to 87 in 97e92a1

	setGasPrice: (newPrice, gasLimit) => {
	newPrice = decGWEIToHexWEI(newPrice)
	dispatch(setGasPrice(newPrice))
	dispatch(setCustomGasPrice(addHexPrefix(newPrice)))
	dispatch(setGasTotal(calcGasTotal(gasLimit, newPrice)))
	},

Can't revert, since it also is messing up number input for the 'Advanced Gas Controls'. Possible need to two convert the Slow/Fast tabs to just numbers.

I can confirm that this isn't because of #6090 or #6091
