Re-opening closed child processes does not update the state of potentially closed parent process

[solth]

Follow-up to #3946 which fixed parent processes not always being closed when all child processes where closed.

When closed processes are re-opened (via "Show closed processes" -> "Edit (closed) process" -> "Task list" -> "Edit task" -> "Change task status"), a corresponding parent process (that has already been closed as well becaues all child processes were closed) needs to be re-opened as well, e.g. it's "sortHelperStatus" need to be updated/recalculated.

No matter how rare such a case might be, since Kitodo offers this functionality it should work correctly.

Understanding questions:

• Is it possible to reopen the parent process manually?
• Is there any point or use in having the parenting process open or not?
• What if the parent process does have a workflow? (We can disable this for individual divisions, but it doesn't say that you have to disable it, or am I wrong?)
