🐞 Description of the bug

Calling list() or list_properties() on root.setup.materials.mixture doesn't return anything, even if mixtures have already been created.

📝 Steps to reproduce

1. Turn on the species transport model and create a new mixture (e.g. by executing define/models/species/species-transport yes mixture-template in the TUI)
2. Call root.setup.materials.mixture.list(). An empty string is returned even though there are mixtures present.
3. Call root.setup.materials.mixture.list_properties(). An empty string is returned. This should probably be throwing an error since the object_name parameter is unspecified.
4. Call root.setup.materials.mixture.list_properties(object_name='mixture-template'). An empty string is returned even though this mixture exists and has properties.

Notably, calling root.setup.materials.mixture.list_properties() where object_name is set to a mixture name that does not exist throws an error, as expected.

The two mentioned methods have base classes that identify them as commands rather than queries. They are designed to simply write output to the Fluent console. In terms of actually extraccting data through the API, note that the mixture object has Python dictionary semantics.
