MCGR: Check correctly for used FillTransparenceGradient

To correctly check using UNO API if a FillTransparence-
Gradient is used it is necessary to check if a Name for
it is set. This corresponds to the IsEnabled() state
of the XFillFloatTransparenceItem in the core.

This was not consequently done that way and e.g. was
done by checking if the FTG was 'default' in the sense
that the StartColor was COL_BLACK. This was never
sufficient and is not with MCGRs, too.

Important in this case is the UnitTest checking for
file fdo66688.docx - the re-export/roundtrip goes
wrong when not doing this correctly.
