solvers::multiphase: Improved CorrectPhi handling for compressible multiphase flows

Browse Source 
The mixture compressibility/density is now included in CorrectPhi for
compressible mixtures, consistent with the compressibility handling in the
pressure equation.  This improves consistency, robustness and convergence of the
pcorr equation.
