   The selenium dont assert well with \n and code, so play safe and just assert line by line.

   This ensure data is saved before render a new form.

  This strips the form rendering from the parameter editor, and placing it as a stand alone editor (separated gadget).

   This allow us following the same API use other gadgets as parameter editors.

This fixes bug https://project.nexedi.net/#/bug_module/20210603-1C66F4F

Improve hateoas support to show shared instances.

It turns out that ERP5 returns
```
'form_id': {
  'type': 'StringField',
  'key': 'form_id',
  'default': 'InstanceTree_viewAsHateoas',
},
```
for the `form_id` in hateoas, so adapt the proxy to do the same.

Currently hateoas support in proxy only lists non-shared instances,
so this always says that the instances are not shared.
