[Bug]: Balance can be 0 (zero) when transactions sum to a positive value

[catch-21]

Describe the bug

Previously having the correct balance displayed in my wallet, on opening my app just now I am shown a balance of 0 even though there are clearly transactions that add up to a positive value. I have a stable electrum server connection and pulling down from the top to refresh does not fix the value. As you can see in the attached recording, the Ledger view highlights that the actual balance does not reflect the expected.

Reproduce

Unsure of how I got here but it doesn't seem to want to correct itself, even after closing and reopening the app.

Please try the following to resolve:

• Navigate to and tap Settings->Advanced->Rescan Addresses

It looks like your utxos may have been cleared out somehow. That's how Bitkit derives it's balance. Re-scanning should resolve it. One way we may be able to prevent this for some users is to perform a re-scan in the background in the event Bitkit detects a discrepancy between ledger and the current balance derived via the utxos.

@coreyphillips Sadly, I have since restored my wallet and am no longer seeing this issue. It's interesting that, if I clear UTxO cache and then pull down on the main screen then the balance corrects itself. This wasn't the case for the state I got myself into. It makes sense for the ledger to be detecting and handling this.

[catch-21]

Happened again (mainnet 20c194faaf1dc812c806fd7b47730f35a4c94286). This time following on from the steps in https://github.com/synonymdev/bitkit/issues/1645#issuecomment-2088529196, I closed Bitkit and reopened it to see if the transactions would correctly update their status as 'removed from mempool'. They had not, and now I cannot view my balance or make any payments.

When attempting send funds the UI is unresponsive and no error. Logs:

 LOG  [TypeError: Cannot read property 'getFeeEstimates' of undefined]
 LOG  [TypeError: Cannot read property 'transaction' of undefined]

When attempting to rescan addresses it fails. Logs:

[pwltr]

Likely fixed by #2210 , closing.

[catch-21]

I have not seen this in any wallet, including the one used when this issue was created. Agree this is probably not going to occur thanks to https://github.com/synonymdev/bitkit/pull/2210. Marking Done.
