[Bug]: Can't pay invoice from other app on same device

[pwltr]

It seems a lot harder to pay from the same device to Bitkit due to node intentionally shutting down on backgrounding. In this case it was CJIT, but probably the same for normal invoices too.

@pwltr @ben-kaufman Should this be closed?!

I reckon recent fixes to iOS might've improved this.

This should fix it #359 so when this is merged
