Fixes #54

Follow-up to #221 - adds in the necessary logic to handle utxo selection across multiple addresses

[bucko13]

Not sure how we want to handle since this isn't really blocking, but I found a small bug where the address level checkbox is deselected when you navigate back to edit a transaction

To reproduce:

1. author a transaction. in my example I have one that's a partial spend from address and a full spend
2. Go to send
3. Go back to edit
4. Notice the select boxes for the address are no longer selected

What could be blocking though is that I selected only 1/2 of the UTXOs from an address however when going back it looks like both are selected. If this is the case and can be confirmed, I'd say this is blocking since we don't want someone accidentally spending all the UTXOs when they only meant to spend part.

Couple of small comments on the code as is, but I think we should address the issue when you go back to edit after clicking to sign

[bucko13]

🤦

[bucko13]

Even worse that we have to do this multiple times in the same method

Don't think you need the >=1 here

Suggested change

	numLocalInputsToSpend >= 1 &&
	numLocalInputsToSpend &&

This is also the case if you navigate away from the send tab (by going to the addresses or receive tab, for example). When you come back you end up in the same state as shown in the screenshot.

I updated things to make sure that it at least shows that the address is now selected (full checkbox, not indeterminate or missing) when you navigate away and/or click edit transaction.

It will require more effort given the current design to actually save which inputs were selected. It would be easier with a larger refactor of how the application is structured.

Don't know if this needs to be a blocker, but this was a weird little bug. If there's only one UTXO in an address, selecting it in the utxo selector doesn't work:

utxo-select.mp4

[bucko13]

Tested happy path and the reset of the utxos if going back to edit and it all seems to work other than the bug identified above. If that is easily fixable, then it'd be good if we can get that in (maybe just disabling that view if only one utxo as a quick fix? 🤷‍♂️ ). Otherwise it LGTM!

Confirmed it works! 👏 🎉
