(issue56) Do not delete the certificate immediately
When the selection changed the remove cert is triggered by
a slection change event in the certificateitem. Deleting
it immediately would delete the trigger of the call.
Instead we deleteLater so that the widget get's cleaned up
in the next mainloop iteration when it is no longer needed.
