fdo#76298: sw: do not start up every OLE object on deletion

First check if it's actually a Chart embedded object; starting up
external processes on Windows for arbitrary OLEs is likely expensive.

(regression from 1ba29be90f7141077f2d079d40dffc2efd4f1a2c)

            without removing it's storage and graphic stream. The chart already removed from formatter.> */
