I discovered a bug in 3.2 in the web profiler and this PR fixes it. This issue has been fixed in the past by #13166 and probably reintroduced by the refactoring we did in the WebProfiler in 3.2. I simply applied the fix to these changes.

To reproduce the original problem, simply clone the current standard edition, create a Form with a Type and add a field after its creation. Once done, try to access the Webprofiler: it will fails with the following error:

> Key "type_class" for array with keys "id, name, view_vars, children" does not exist in @WebProfiler/Collector/form.html.twig at line 460.
