BIP-0322: remove address optionality for PoF

Browse Source 
This is cleaning up an artifact that was left over from #1352.
The alternative to removing the optionality of the address
would be to assume OP_TRUE in case of an empty address.
But that sounds like it could open up any number of potential
vulnerabilities.
And a user still has the ability to use an OP_TRUE script
in a p2wsh or p2tr address.
