Example file from Writer master

Writer crashes if the table background color is unset from the sidebar.

1, Open attached file with a simple table having cell background color.
2, Click in the red cell and using the TableCellBackGroundColor UNO command from sidebar select "No fill" option.
3, Crash.

This happens with GTK3 vclplug, bug not with gen or qt5.
The TableCellBackGroundColor command is available from the Table toolbar but does not cause crash if used from there.
