fix: improve linking

[reneaaron]

Improves scheme handling

Improvements

• Delay start of camera for link intents
• Improve handling of human readable payment information (e.g. lightning:hello@getalby.com should display as hello@getalby.com)
• Fixes lightning: and LNURL are being shown on the confirm payment and success pages when they should not #128
• Fixes [Bug] "Pay in Wallet" - Wallet won't load invoice correctly #83

Testing (and for future reference)

To simulate opens during development:

npx uri-scheme open exp://127.0.0.1:8081/--/[LIGHTNING_ADDRESS] --android
npx uri-scheme open exp://127.0.0.1:8081/--/[LNURL] --android
npx uri-scheme open exp://127.0.0.1:8081/--/[BOLT11INVOICE] --android

Test vectors

• lightning:hello@getalby.com
• bitcoin:bitcoinaddress?lightning=lnbc1...
• lightning:lnurl
• lightning:invoice
