This commit adapts tests following recent changes on the helpers.
The main change is that addMockEnvironment (and all functions using
it) are now async, as they need to wait for services to be started.
Currently, the method `on_attach_callback` is never called on any Widget in the
systray.
Calling `on_attach_callback` is required if any systray widget uses an OWL
component via the ComponentWrapper. Without the callback, the component is never
considered mounted to the DOM and no event handler is triggered.
