On ag/21680045 I copy the previous mOccupied but the right thing to do is to
create a new one with all the views information.
Some test stoped running inadvertently that's why we didn't catch this issue.
There is a separate cl with the test to ensure we can catch it later on.

ReorderAlgorithm will now handle all the logic associated with the
reorder. Basically all the logic associated with a reorder in CellLayout
was copy and pasted into ReorderAlgorithm.java.
