BUG: VM status not refreshed correctly

[romu70]

Test case to reproduce the issue

Pre-conditions: your VM is running and shown as "Active" in WebVirtCloud

1. Click on the button to shutdown the VM and wait for the VM to be off
   -> Expected result when the VM is off: it's shown as "Off"
   -> Actual result: WebVirtCloud still shows the VM as "Active"

Workaround: Changes the current page (for instance by clicking on "Computes" and go back to the "Instances" page.

For me too.
