tdf#117137: DOCX import: don't try to set grab-bag as UNO prop

This modifies commit a6f2199e9888cb75960f1d35034bd44fb45e5565
"DOCX import: don't try to set grab-gag props as UNO props"

Perhaps that commit should simply be reverted, but I will trust
that the commit was mostly OK and simply adjust the logic so
that *InteropGrabBag is ignored as before.

Doing this resolves MSO being unable to open a specific document
and LO missing some numbering during LO round-tripping.
Probably these are just side-effects from other locations in the
code that couldn't deal with these unexpected properties. For
example, the numbering.xml file is malformed, since it is
missing the w14: namespace.

Unfortunately, I failed in my attempt to create a minimal
test document.
