We want to avoid that a `setTimeout` started in one test has an impact on other
tests. This is especially true with the status update loop. Since mail_service
is used in multiple tests, the safest solution is to patch timeouts everytime
we make a call to getMailServices.
There is no need for an unpatch, the patch become the default behaviour until
the page is refresh at the end of tests.
It is possible to manually add the patch after calling `getMailServices`
```
this.services = mailTestUtils.getMailServices(this);
this.timeoutMock = mailTestUtils.patchMailTimeouts();
```
This can be usefull if we want to get the timeoutMock to simulate time changes.
