In the QUnit test suite, we have cleanup code that runs after each
test to ensure that event listeners, setTimeouts... registered
during a test are removed. This is particularly useful for services,
as they do not have a "destroy" function to cleanup those handlers
they would have registered at startup. Side note: they don't
because it would only be useful for tests, as a service lives
forever in the prod environment.
Before this commit, that cleanup code didn't remove callbacks
registered with a setInterval. Moreover, we didn't remove event
handlers bound on document.body either. As a consequence, there
were memory leaks in the test suite (e.g. callbacks of the tooltip
service), and some crashes could occur if the user interacted with
the window after test completion.
