rABCc78b5ff801c4: [ecash bip21] Make empty OP_RETURN out of spec
Summary

I can't think of a good reason to include an empty OP_RETURN output. I could though imagine it happening by accident if someone is generating bip21 params.

Make this out of spec so implementer validation can catch it.

Test Plan

Review summary, attempt to think of counterexample good reason for empty opreturn in params
