RTF IMPORT : considere OLE objects as pictures

resolve fdo#53594 : Import RTF file but ole are not well positioned in
table/cells

If the OLE object is in a container, don't try to import it as
OLE object (use the \objdata element) but use the \result element which
is the appareance of the object (it's a picture).
