Workflow Link Broken in Workflow Emails

This has probably been broken for a while, tested in latest release:

When emails are generated thru the workflows and a "notify assignee" sub-action is present, then the email template (/dotserver/tomcat-8.0.18/webapps/ROOT/WEB-INF/velocity/static/workflow/workflow_email_template.html) sends an email:

This email template expects that a ${workflowLink} is being set:

     <tr bgcolor="white">
         <td align="right" valign="top">
            <font color="gray"><b>$structureName:</b></font>
        </td>
        <td>
            <a href="%24%7BworkflowLink%7D">$!{workflowTaskTitle}</a><br>
        </td>
    </tr>

However, this workflow link ends up being sent with some Null values for id's at the beginning of the pathing, thus resulting in a 404, as shown in this example:

  
https://demo.dotcms.com/c/portal/layout?p_l_id=&p_p_id=workflow&p_p_action=1&p_p_state=maximized&p_p_mode=view&_workflow_struts_action=/ext/workflows/edit_workflow_task&_workflow_cmd=view&_workflow_taskId=9dcb1888-2ce3-482a-8675-44464ef5bce0  

We should fix the way this workflow link is built, so that after login, the user is brought to the detail of the specific task (permissions permitting)
