Remove enzyme (#640)

The test that was added is not a good test. If we want to test things, we should be testing logic that is error prone such as all the mouse handling logic and state management. Adding a test for something trivial as displaying a list of data is just going to be annoying when we eventually change the UI and the test breaks.

Since this is the only test using enzyme, I also removed enzyme. We can add it back if we want to test a component using it.
