[Bug]: 'Reserve Balance' error shown when tapping available spending balance in send flow

[catch-21]

Describe the bug

After scanning/pasting an LN invoice that doesn't specify the amount the send flow opens and the amount can be input. Tapping on the Available amount here always shows an error.

"Reserve Balance"
"The maximum spendable amount is a bit lower due to a required reserve balance."

This seems unnecessary. It could be because the fiat amount shown is a bit lower once applied.

Reproduce

1. Produce LN invoice without an amount
2. Scan or paste the invoice into Bitkit
3. One the 'Bitcoin Amount' screen is shown, tap the AVAILABLE amount
4. Observe 'Reserve Balance' toast error
