tdf#130362 sw: fix anchoring of inline math objects

Regression from a7528cd6f17ea5c5b29e7d607e54c62de0d9e7db (sw: insert
image: set anchor to at-char by default, 2019-11-18), that defaulted to
at-char anchoring for charts and images.

What was not considered is that math objects had a previous as-char
default (not to-para), and that is supposed to be unchanged.
