Only copy perfPhaseRates if number of perforations is equal.

Browse Source 
The number of perforations may change due to completions beeing shut.
If the number of perforations changes the perfPhaseRates are set to
equal the wellRates/(number of perforations) instead of the values from
the previous time step.
