Have TriggerResults see all transitions

[Dr15Jones]

The FastTimerService requires that all modules see the beginJob transition
in order for it to register that module. A recent change to the framework made
the TriggerResults only see Stream based transitions since that is all it needed.
This change makes TriggerResults see all transitions again.

This fixes the last problem still left open after #636
Checked that this compiles and all framework unit tests pass.

@nclopezo can you please test this with a full build? It might have sense to have 4.64 tested as well.
