Add seam space for performReorder in MultipageCellLayout
In the other method createAreaForResize we add 1 to the cellX
to account for the seam in the Multipace CellLayout but we don't
account for that on performReorder and we need to add a cellWidth
Also, some methods are not running when the seam is added so their
result are wrong. Now all methods are being accounted for.

Test: atest ReorderAlgorithm
