Issue: the spring step definition injection does not work

Autowiring one step definition class to a field of another step definition class does not work any more (since v1.1.4?).

It has been noted, in a [comment](https://github.com/cucumber/cucumber-jvm/issues/569#issuecomment-26699067) on another spring issue and on the [mailing list](https://groups.google.com/d/msg/cukes/q95I0s1r80g/tc1yzmU2fHMJ), but no issue has been created for it.
