[FIX] website: re-render the visibility selector on field label change

Steps to reproduce the bug:
- Add a form on the website.
- Add two fields on the form ("A" and "B").
- Change the conditional visibility of "B" and put it to "Visible only
if".
- Change the label of "B" and set it to "A".
- Try to change the dependent field.

-> "A" is still on the list of the eligible dependent fields. It should
not be the case as setting this field as a dependent field would create
a circular dependency.

To solve the problem, the file visibility selector is rerendered after
modifying a field label. Because of the `_findCircular()` check at the
rerendering, the problematic field will not be displayed in the list of
of the eligible dependent fields.
