sd: enable insert graphic when UNO command has URL file argument

When LOOL requires to insert a graphic, it uses UNO command ".uno:InsertGraphic",
and the corresponding URL file image argument.

However Impress, ignores URL file image argument, and by default
pop up a dialog, so no image is inserted in LOOL.
