Current issue: Task Timer Reassignment by Scripted Assignment within Workflow is not working

Steps to reproduce (based on PTR-1629):

1) Create 2 users with screenName 12test and 13test.

2) Import the workflow below, but change the following: 

For the 3 entries that contain:

import com.liferay.portal.kernel.service.UserLocalServiceUtil; user = UserLocalServiceUtil.getUserByScreenName(20096, "12test");

Change "20096" to your own local portal companyID. You can check it by going to CP > Search > Field Mappings > liferay-<companyID>

3) Associate the workflow with blog entry.

4) Create a new blog entry and wait 1 minute

5) Impersonate 12test and check My Workflow Tasks

Actual result: the task is not being reassigned to 12test after 1 minute

Expected result: the task should be reassigned from 13test to 12test after 1 minute
