Outline folding: Check frame area is valid before using pointer to
saved outline frame
It seems when a frame is removed it is not immediately destroyed, so a
pointer to the removed frame may not be a null pointer. This patch
checks for valid frame area definition before using the save outline
frame pointer with intention to fix an intermittent crash occurrence
when an outline paragraph is removed.
