0031242: Scaling with different coefficients along axes produces invalid shape

GeomConvert_1.cxx:
Creation periodic BSpline surfaces from trimmed periodic surface if trim is boundaries of periodic domain is allowed

BRepTools_NurbsConvertModification.cxx:
Checking domain of 2dCurves if surfaces are periodic is added

Test case tests/bugs/mesh/bug30008_2 is modified according to current behavior

Test case tests/bugs/modalg_7/bug31242 is added
