No update option for JIRA Macros as a system add-ons

Steps to reproduce:

1. Install Confluence 5.6.2 OR 5.4.4
2. Go to Manage add-ons.
3. Expand the System add-ons.
4. Search for JIRA Macros

Expected Behavior:

In Confluence 5.6.1 bundled JIRA Macros is 5.6.2 while the latest version here is 5.6.11 at the moment. So, expected behavior is Confluence needs to shows the update option for this plugin.

Expected Behavior:

The only way to update JIRA Macros is through the manual update/install from the UPM.
