Describe the bug
Multiple loop steps can be added to a single automation step as the button to add the loop is still clickable when a loop is already present. This causes the step to not loop over anything.

To Reproduce
Steps to reproduce the behaviour:

1. Create an automation
2. Add a step with a loop
3. Verify it works
4. Click Add Looping on the same step
5. Another loop step is added behind the scenes, automation now loops over nothing returning "status": "no_iterations" on the response

Expected behaviour
After adding looping to a given automation step, the Add Looping button for that step should be disabled or hidden.
