Work harder to find the Invoice

[HamishMacEwan]

Description of the Feature or Idea

Rather than interrupt the flow to announce the invoice is invalid (a trailing " " included in the copy, I'm sorry, let me highlight that again and copy it without the trailing blank) please do your best to find the invoice wherever it is in the input.

Existing Example(s) of Feature

https://lightning-wallet.com/ is a target for sharing on Android, and when I share:

{
  "invoice": "lnbc15360n1p0v3tzlpp58ns2xp7yues4dkag8483972mxx5l8d5fm63z2zpy5ljvdjr848kqdp9gf5hgsmvda6kguewwd5r5grpd3cxsctjvsknzxqr8pqcqp2rzjqds2g84cc0lqj7pw7mycft9mqqasu84uflss4cqm4v8gp4mxrry0gzvrcuqqnysqqqqqqq05qqqqqqgqpcg5f3w9vqh7dxf30e6wv2m5dcfg4h7zh8x22yuze3s400qe6zq0l3ktk5mqu2mw3ajw4vn0stsqe5jyw47kts4ssnp8v2353p4s5muvgpqxaclr"
}

It doesn't complain, it finds the invoice within the string and offers to pay it.

Joule, context menu on Windows 10, won't even appear if that JSON fragment is highlighted.

Joule appears for that string, trailing white space and all, then chokes:

I think this is case for the Robustness Principle, "Be conservative in what you send, be liberal in what you accept" https://en.wikipedia.org/wiki/Robustness_principle

Seems totally reasonable, I'll try to make a forgiving function for parsing invoices from user input, and use that everywhere I can. Thanks for the suggestion.
