remove the field "customFieldsGroup" on custom field creation

The customFieldsGroup field is hidden when creating a new customFields.

The customFieldsGroup is retrieved from the url (`customFieldsGroup` value in the URL).

This should ease the task for administrator and be consistent with the UI which group customFields into customFieldsGroup.
