sw: fix assert on layout of ooo63564-1.odt

The problem is that some SwTextFrames (1415 in particular) inside the
follow-flow-row of a table move backwards, during(!) which the
follow-flow-row is deleted; i.e., the SwTextFrame was already moved
backwards by the pNewUpper->Calc() in MoveBwd(), then it is Cut and
Pasted at the end of pNewUpper, when it is actually already a lower,
somewhere in the middle...

This triggers the assert in SwFrame::PrepareMake() that was added in
commit e14056e6e88d9b8d988b7b88b2776a8fc952031b

Prevent this by using the IsDeleteForbidden() check that was introduced
in commit 0005b330eaed0b5559042d2597fb45e0c9125d7e; this is similar to
how MoveBwd() already locks section frames to prevent such problems.

Ultimately a regression from 18765b9fa739337d2d891513f6e2fb7c3ce23b50.
