Fix regression of non-regression tests

- Coplanar faces filter (SMESH_Controls.cxx)
- Convert to quadratic (SMESH_MesherHelper.cxx)
- Missing Compute item in mesh pop-up in presence of a sub-mesh on compound only (no other algos) (SSMESHGUI_ComputeDlg.cxx)
- set checkAll=False in call of SMESH_Gen::IsApplicable() (smeshBuilder.py)
