0027575: Reading STEP file gives an empty result

Browse Source 
Exception is raised during translation BSpline curve having only one unique knot.
Protection for such case was added
Added protection against exception during reading BSpline curve with number of control points equal to 0
Added protection against exception due to using null binder during writing XDE document

Test case for issue #27575
