The addInfoMessage disappears too quickly when redirecting a Record Producer in Service Portal.
Steps to Reproduce
1. Create a record producer using the OOB 'Create Incident'.
2. In the Script field of the record producer insert the following:
gs.addInfoMessage('This was just created.');
producer.portal_redirect = '/sp?id=index';
3. Navigate to Service Portal and submit the Record Producer.
Observe the info message disappears in less than a second due to the redirection, instead of staying persistent like in Service Catalog.
