tdf#106970 DOCX import: don't collapse para auto space for different nums

Commit 1bf7f6a1a50ee9f24a3687240fe6ae390b905a6b (tdf#106690 DOCX import:
fix automatic spacing before/after numbered para block, 2017-04-04) made
sure that autospacing is only collapsed in case the adjacent text nodes
both have a numbering rule.

It turns out there is an additional condition: even if both text nodes
have a numbering rule, do the collapsing only in case they have the same
numbering rule.
