twoPhaseEulerFoam::twoPhaseSystem: Ensure inlet flow of BOTH phases matches the BCs

Browse Source 
Previously the inlet flow of phase 1 (the phase solved for) is corrected
to match the inlet specification for that phase.  However, if the second
phase is also constrained at inlets the inlet flux must also be
corrected to match the inlet specification.
