Regression from commit 4ab658b56f (RTF
import: implement support for tables inside text frames, 2013-06-16),
the problem was that both the outer "textbox" and the inner "picture
frame" object had a shapeType property, and the properties were stored
in a vector. So by the time RTFSdrImport::initShape() looked up the
shape type for the inner shape, it thought it's not a picture frame,
leading to data loss.
