Fix redirection after handling a task with temporary permission - HTTP 403

The scenario is the following:

1. login as Administrator
2. create a user test
3. create a document MyDoc and block permission inheritance (user test cannot read this document)
4. start a serial workflow and request user test to validate MyDoc
5. logout from Administrator and login as test
6. navigate to the document MyDoc and start the task from the MyDoc page
7. validate the document in the task form
8. you are redirected to the latest document displayed before handling the task which is MyDoc to which your temporary permission has been revoked => HTTP 403 is displayed

   Privilege 'Read' is not granted to 'test'

Expected result: a non-error screen is displayed to the user, such as his home page.

NXP-27071 does not handle this case.
