Fix for 'New Folder' is not getting added to chrome://bookmarks/ through 'Organize' menu after adding 'addPage'

When we do add page then new node is added, but that node in not yet
commited, and have id as 'new', so we should not consider as the selected
item.
Changes added so that when the entry is not commited,
it should not be considered for calculating the nextIndex value.
