* Fix constraint set handling for installed constraints
A rather subtle bug. The code was actually correct but the transitionsTo
assertion was not accounting for a transition between the case where
a package's available version had been excluded and then the whole thing
got excluded by a version constraint. It counted one side as a loss
without a corresponding gain on the other side.
