Piro: before adding observer to Tempus, first clear the composite vector

[sconde]

when setting tempus observer, first clear the vector of observers to avoid adding multiple copies of the piro tempus obsevers.

also define integrator output in TempusObserver here since the composite
vector is cleared.
