The content of submenu "Add-ons" doesn't update automatically

[Giova84]

I have noticed that if I put add-ons (obviously as HPKG files) inside the folder /boot/home/config/add-ons/Tracker, they doesn't appear at the first shot. To see them listed in the submenu "Add-ons" in Tracker, I have to quit and then restart the Tracker. Here on hrev48327 this happens every time, is always reproducible (with any add-ons). I have also noticed that if I add another add-on inside that folder, this will update the list and I can see the add-ons which I have previously installed, without quit and restart the Tracker.
