test-runner: Disconnect display-opened signal on destruction

Browse Source 
When running multiple tests at once (with --all) as in the
installed-tests cases, we may open and close the display multiple times,
this leads to setting the alarm filter each time that the x11 display is
opened (causing a critical error) because we never disconnect from the
::x11-display-opened signal.

So disconnect from the signal on test destruction, to avoid this to be
emitted multiple times.
