Autowatch does not work

NOTE: I moved this issue to the Service Desk project because a partner helped us discovering that the issue is related to Jira Service Desk 4.4.1 and not to Jira Software.

Issue Summary

2. Set the Autowatch function to Enabled on the system or in a user profile level.
3. Create an issue.
