IfcConversionBasedUnit's Name is case insenstive and it was producing UI errors.
Noticed working with file from Revit Ryan attached in #6374

KeyError: 'FOOT'
1) get_object_main_axis - replace branching with just max between dimensions. There is a small caveat that previously for `x,y,z=1,2,2` it would return 'x' but now it returns 'y', but I'm not sure if 'x' was really intended here.
2) get_length - current implementation does the same as get_linear_length
Ping @maxfb87 just in case.
This solution brings new questions to #5938.
Currently, we lack a reliable way to calculate the existing x_angle only based solely on the extrusion direction. For example, a 30 degree angled extrusion with positive direction has the same extrusion direction as a -150 degree angled extrusion with negative direction. The difference lies in the object's rotation.
This means that things can get messy if the user changes the object x angle somehow. We may need to explore alternative approaches.
