REVISION SUMMARY
  Due to concurrency in PHD2 it might happen, that a last guiding step is executed after a pause command has been successfully executed. This can create problems with the Guide module, since the Guide module assumes automatically being in state GUIDE_GUIDING if it sees a guiding step.
  To resolve this, the PHD2 module no longer guesses the state but it re-aquires it from PHD2.
  
  This method could be used in future in other situations as well. Due to try to avoid any regressions, I only resolved this single code place. If it turns out to be stable, we could refactor other places as well.

TEST PLAN
  This specific situation is difficult to test. Since a central method handling a received state information has been refactored, please test all situations where PHD2 changes its state.
