- The test for overriding a theme (uploading a theme with the same name as the currently active theme) doesn't test the right codepath
- It incorrectly assumes uploading the same theme twice results in an override, but this is only true for the active theme
- This change splits the override test out into it's own test, and only tests overriding by changing the active theme first
- Also fixed a minor comment type whilst here
