ENYO-1870: fix issue where setting height to 101 then moving item causes item to disappear by making sure that updatePageHeight won't set a page height to 0 but instead use 1 which avoids hitting bad estimation code.
Refactor enyo.List.positionReorderedNode to be part of reorderRows and include the moveItemToDiffPage code
