Old clients expect "L402 macaroon=..." in the first WWW-Authenticate, while the protocol [1] says it should be "WWW-Authenticate: L402 macaroon=...", so send both LSAT and L402. LSAT must be sent first, to maintain backward compatibility with older clients. [1] https://github.com/lightninglabs/L402/blob/master/protocol-specification.md
