Issue Summary
The "Activity Stream" gadget shows "An error occurred while trying to retrieve recent activity" error while loading DVCS information.
The following error is presented on HAR file and atlassian-jira.log:

Steps to Reproduce
- Install Jira Software 11.1.1.
- Configure Git as an application link.
- In DVCS accounts, link a Git account.
- On the Git side, in a repository:
- Add a new file.
- Commit the change and include a Jira issue key in the commit message.
- In Jira:
- Refresh the repositories.
- Open the Activity Stream gadget again.
- The gadget fails with the same error.
We can see this behavior in the recording here:
