Cutcell error with mesh refinement

[rmcdermo]

@marcosvanella Try this case:

FM_15cm_Burner_C2H4_20p9_0p5cm.fds.txt

I get this error:

FM_15cm_Burner_C2H4_20p9_0p5cm.err.txt

The case worked fine with uniform 1 cm mesh.

Changes on the mesh topology from some blocked fine cells are not getting transferred to the coarse side in the refinement region through the hood. I'll fix.
