Got report that there was an issue with get_parts not returning all parts if there are multiple IfcRelAggregates involved though it is valid ifc. Fixed the same possible issue for ContainsElements, IsNestedBy

Noticed working on #5596 and #5708 a few issue when pset template is changing the prop types.
E.g. prop had string data type and now template suggests that it should be a float.
Previously, it might error trying to cast a string to a float. Now it will show a float until user will set it to null, then next time it will be loaded from the template data type.
Another example - prop was a string and now it's a boolean. Previously, it would be cast to boolean implicitly. E.g. "test" -> bool("test") -> True. And if user wouldn't be paying attention then enabling pset editing and saving it would make them lose "test" value.

I guess by accident in d443c5e I've made this method too strict and it broke get_references using it for IfcPropertySets. Maybe it's a good idea to make it more strict in the future, for now just restoring the previous behaviour.
`transition_curve.py` is now obsolete and has been removed.
A python port of IfcAlignmentHelper.cpp has also been started.
It needs further development to accommodate vertical alignment.
Previously it would show obscure error like:
RuntimeError: Type held at index 0 is class Blank and not class std::vector<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,class std::allocator<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > > >
