pay: don't require description for hashdesc invoices (i.e. undeprecate).

Browse Source 
Since we didn't hash the descriptions properly (see previous commit), we
cannot immediately deprecate omitting the descriptions (since you'd
have to omit them for backwards compat!).

And move the "must have description or hash" test into bolt11.c core.
Changelog-Deprecated: `pay` has *undeprecated* paying a description-hash invoice without providing the description.
