tdf#135014 sw: fix crash exporting numbering to DOCX

It can happen that the default SwNumRule of a SwList isn't used by
anything directly, but there are other SwNumRule associated with that
SwList and then the DOCX export needs to export it as an abstract
numbering definition.

(regression from 632ee9aae6d5f3cf08b6d6b2789310c20db713b7)
