Example Object Store keys don't always include project Id

[DerekMelchin]

Expected Behavior

All Object Store key examples include the Project Id in the OS path

Actual Behavior

Some examples that use the Object Store don't include the Project Id in the OS path. For example, this one just uses a "model" key. If a member already has a "model" key in their Object Store and then tries to run this example, it won't work.
