sw: avoid deleting the iterated SwRowFrame on tdf104188-4.odt
The change in commit 1e6dec4b4313212a3bdc6bb06155fd65e795368b
was not enough to fix this problem.
SwContentFrame::CalcLowers() may move a SwTextFrame to the previous
page; in that case Calc() on the upper is a bad idea because it may then
call RemoveFollowFlowLine() and delete the SwRowFrame that is being
iterated.
There is one other (unknown) bugdoc with this problem, let's hope it's
fixed as well...
