tdf#116925 sw: consider fill styles of shape for in-textbox auto color

Automatic color is determined in SwDrawTextInfo::ApplyAutoColor(), but
it uses this function to determine the background color.

Be consistent and consider the same background in both the
shape-with-editeng-text and shape-with-sw-text cases.

(cherry picked from commit f966767e1ccfa432da33e1a0fd6de69e17a36bc3)
