Refactor test_image to plot @circuit.png instead of test_logo.png (#2922)

So that we don't need to pull test_logo.png from dvc,
or run test_logo first to generate the image.

* Add @circuit.png to cache
* Remove dvc pull step from ci_tests_legacy.yaml
* Try running test_image on Windows to see if it crashes
