tdf#150402 Correct wrong Bound of Shape in Slideshow
Added and use mbContainsPageField that gets set in
prepareHyperlinkIndices() which has to be run anyways,
so this will cause no change in execution speed.
It lets us detect the potential error case that a
PageField is contained in the Text of the Shape.
That is a hint that maBounds contains the wrong Range
and needs to be corrected.
For more backgrund information please refer to
tdf#150402, Comment 16.
