solver doesn't creates the PIMPLE class

Summary

When trying to use the PIMPLE-mode with chtMultiRegionFoam the solver always runs all of the outerCorrector loops without reading the residual control. It looks like the solver doesn't create the PIMPLE-class properly. (See log-file)

Steps to reproduce

Starting of chtMultiRegionFoam in PIMPLE mode with residual control for different regions.

Example case

See attached: Bug_report.zip

What is the current bug behaviour?

Solver Runs all outerCorrector loops even if all given residual controls are fulfilled.

What is the expected correct behavior?

Solver should leave outerCorrector loop as soon as all given residuals are fulilled.
