Petru Conduraru 1416af510a style.assign_representation_styles: fix crash on IfcPresentationStyleAssignment #7883

When replacing a style on an item whose previous IfcStyledItem wraps its styles
in the deprecated IfcPresentationStyleAssignment, and the assignment is not
being reused (use_style_assignment is False, e.g. an IFC4 file authored by
AVEVA E3D), the else branch called remove_same_type_styles(style_assignment)
with style_assignment still None, raising
AttributeError: 'NoneType' object has no attribute 'Styles'. Operate on style_,
the assignment found in the current iteration, instead of the accumulator.
Verified red-green with a minimal IFC4 file using IfcPresentationStyleAssignment.
