`python test_runner.py`
Test that a regular BIP72 payment request still works:
- Generate a payment URI: `curl -L -H 'Content-Type: application/json' -d '{"outputs":[{"address":"1NLcNpAaBBMekgBZk7NxwdxwtSUTfTV8Aq","amount":560}],"currency":"ecash"}' https://pay.badger.cash/create_invoice`
- Run `./electrum-abc`
- In the send tab, paste `ecash:?r=https://pay.badger.cash/i/JFPTG` (replace the URL with the one returned by the above `curl` command
- Send
