In tests we could attempt to click the preview button when it was not enabled yet, causing a noop and a future failure. This fix ensures we try to find (and wait) for an enabled button.
This should help with this specific flakey:
```
Failures:
1) Admin Customize Form Templates when visiting the page to create a new form template should render all the input field types in the preview
Failure/Error: find(".form-template-field__#{type}").present?
Capybara::ElementNotFound:

In tests we could attempt to click the button before it was enabled and it could also not be visible on screen. This commits attempts to solve both problems.
It should solve this failure:
```
