sw TextGraphicObject: fix GraphicURL handling in the descriptor

Commit dfee7d93b4e863d673c45921f79bb876b5738ea6 (sw: get rid of
FN_UNO_GRAPHIC_U_R_L and "GraphicURL" property, 2018-03-08) removed
support for string-based graphic references, then a later commit
restored the setter. But one scenario (when setting the graphic URL
before inserting the text graphic object) was still unsupported for real
URL setter; restore that as well.
