Miklos Vajna c7307c7725 fdo#82191 sw::DocumentLayoutManager: copy textbox content of draw formats
The SwFmtCntnt, i.e. the content of the draw format was already copied,
but that's only a pointer to the real content: instead duplicate the
real contents on copy&paste, that's how we copy fly frames as well.
