Make grid size migration less confusing for users.

Grid size migration is a confusing experience for users because the
content of the grid is not predicatable to the user. Part of the reason
was the dedupe logic which merges items from new grid into old grid,
this mean if user removes an item, change to another grid and go back,
user will see that same item re-appears.

This CL keeps the content of target grid the same as source gird, i.e
user will will get the exact same set of app icons/shortcuts/folders and
widgets (if size permits) across grid sizes. The only difference being
their placement in the grid.
