reacting*EulerFoam: populationBalanceModel: Improvements to updates of mass transfer rate and sources

The update of mass transfer rates in the population balance system is
now done at the same time as other source terms. This benefits
synchronisation of the mass transfer rate and the source terms and
prevents the system converging to an incorrect state.

Patch contributed by VTT Technical Research Centre of Finland Ltd and
Institute of Fluid Dynamics, Helmholtz-Zentrum Dresden - Rossendorf (HZDR).
