data: withResolvedContribs: fix bad availability filter

Was based on contrib.thing, which is always present.

These steps are meant to filter based on the availability of
each contribution's artist, since that's a forward reference
that may be unavailable in given artistData.

Introduced alongside raiseResolvedReferenceList in
commit 65ff7444 (i.e. 11/16/2024).
