Ruslan Kuprieiev c827654fe7 tests: use mocker instead of unittest.mock where possible
Had the "pleasure" of finding a mocker.patch leak into other tests and one
of the suspicions is that mixing unittest.mock and mocker might be somehow
related.

In any case, we should use mocker where possible anyway.
