fix Invalid Read on conversion of ooo95991-1.odt to pdf

"Prepare" can delete the Portion belonging to the SwTxtFrm
and replace it. Prepare knows this and re-fetches it if
that happens. But Prepare can call itself and the outermost
Prepare doesn't know that the innermost Prepare replaced
the SwTxtFrm (and re-fetched it for the remainer of the
innermost Prepare).

So bubble out that it was re-fetched so the outer most
one re-fetches too
