Fix execution of Automation scripting with parameters

The parameters passed to an Automation Scripting seems to be cached, hence the second time the script is called, it used the previous values.

Here is a scenario to reproduce the problem with the attached jar

1. Navigate to the User workspace as Administrator
2. Create a Folder named Folder
3. Click on the New button
4. Choose Note document type
5. Observe that the title has the value "A Son of Folder"
6. Navigate to the User workspace
7. Click on the New button
8. Choose Note document type
9. Observe that the title still has the value "A Son of Folder"

I've added some logging in the Automation Chain (ERROR level) and in the Automation script (WARN level) and I observe that:

• the value read in the Automation chain is correct
• the value read in the Automation script is incorrect the second time and seems to be read from a cache

14:33:03,414 ERROR [logger] Parent = /default-domain/UserWorkspaces/Administrator
14:33:07,147 WARN  [Console] parent path: /default-domain/UserWorkspaces/Administrator
14:33:07,233 WARN  [Console] parent: DocumentModelImpl(c93b2809-58ef-4590-88bd-1662e60fcacf, path=/default-domain/UserWorkspaces/Administrator, title=c93b2809-58ef-4590-88bd-1662e60fcacf)

14:33:21,745 ERROR [logger] Parent = /default-domain/UserWorkspaces/Administrator/Folder
14:33:22,744 WARN  [Console] parent path: /default-domain/UserWorkspaces/Administrator
14:33:22,780 WARN  [Console] parent: DocumentModelImpl(c93b2809-58ef-4590-88bd-1662e60fcacf, path=/default-domain/UserWorkspaces/Administrator, title=c93b2809-58ef-4590-88bd-1662e60fcacf)

Code of the Automation Chain

- Context.FetchDocument
- Log:
    level: error
    message: "Parent = @{Event.context.getProperty('parentPath')}"
- javascript.setDefault:
    parentPath: "@{Event.context.getProperty('parentPath')}"

Code of the Automation Scripting

function run(input, params) {
  var properties = {};
  Console.warn("parent path: " + params.parentPath);
  var parent = Repository.GetDocument(null, {"value": params.parentPath});
  Console.warn('parent: ' + parent);
  var title = parent.getPropertyValue("dc:title");
  properties["dc:title"] = "A Son of " + title;
  input = Document.Update(input, {
      'properties': properties,
      'save': false
  });

  return input;
}

The bug cannot be reproduced in 9.1 maybe a consequence of the work done by NXP-21294
