Brief description

Calling getattr on dynamic modules in openpype (openpype_modules and openpype_interfaces) does not behave as expected because is raising ImportError instead of AttributeError.

Changes

• dynamic module has __name__ attribute (where is stored it's name)
• __getattr__ method raises AttributeError instead of ImportError

Testing notes:

Run script in python interpreter console

import openpype_modules

# This should return None and not crash
getattr(openpype_modules, "missing_module", None)
