Upgrade: change logic for update path for files

For going from version A to version D, it uses to run the SQL files in
that order: A -> B -> C -> D -> A-cleanup -> B-cleanup -> C-cleanup ->
D-cleanup. If you had upgraded each version separatively you would have
run A -> A-cleanup -> B -> B-cleanup -> C -> C-cleanup -> D ->
D-cleanup.
This change the logic to follow the same path if you are jumping over
versions.
