[TASK] Only show active packages in PackageStates.php

Update the version to 5 and include a list of active packages,
everything else is stored in the core cache, and not needed
to be stored.

Note: the order of the package keys in the DependencyResolver
tests is changed intentionally. The order created by the
DependencyResolver has not changed. The tests did not
detect any difference in the order because we had an
associative array before (now it is indexed where the order
is relevant).
