To be fair, currently the test is a bit pointless (as it has no reason
to be a `SkinnableTestScene`, it gains precisely nothing from it - all
that is shown there is some generic components on song select). But that
is no worse then `master`, so look away for now.
As it turns out, the tightening of hitcircle lifetimes in editor caused
the test to fail, since the objects were too far apart and at the
starting time of the test, the first object was fully faded out and as
such not alive, therefore leading cyclic selection to fail to select it.
To fix, bring all three objects closer together time-wise so that this
does not happen and the test can continue to exercise its original
behaviour.
