BIP353 handling confused by presence of .well-known

[Sjors]

Using iOs v2.3.1

I have both BIP353 with bolt12 (with a DNS record) and LNURL configured (using BTCPay and a .well-known).

When I copy-paste ₿sjors@sprovoost.nl into the send screen I get the following popup:

The ₿ prefix makes this unambiguously a BIP353 thing, so imo it shouldn't even try the .well-known/lnurlp URL.

When I paste my address without the ₿ prefix it gets the BIP353 variant, as expected (see #589).

The payment itself fails with "could not retrieve payment details", but I believe that's a known issue when paying to CLN - and unrelated to this issue.

@robbiehanson this should be fixed by 58d67c8 (we should not fallback to LNURL if there's a ₿ prefix).
