Steps to Reproduce

1. Go to the execution environments page
2. Click "Add execution environment" and create an EE named "foo"
3. Repeat step 2 and create another EE named "foo"
4. The second one fails mysteriously. If you look at the API calls you'll see this is because it's a duplicate name, however that's not communicated to the user on the UI at all

Actual Behavior

Error messages are not being displayed on the form.

Expected Behavior

Error messages should be displayed alongside the broken fields.
