refactor: use address_to_scriptpubkey to retrieve addresses scriptpubkey

This commit updates the code by replacing the RPC call used to
decode an address and retrieve its corresponding scriptpubkey
with the address_to_scriptpubkey function. address_to_scriptpubkey
function can now decode all addresses formats, which makes
it more efficient to use.
