test: use monkeypatch to safely handle monekypatching
Tests are unittest based, so pytest fixtures can not be used by adding
them to the function signature.
Augment the inject_fixtures to inject monkeypatch as
self._monkeypatch.
Use _monkeypatch to patch the three functions replacing the code that
manually did the patch. Remove the code that rolls back the manual
patching as monkeypatch rolls it back automatically when the test
function exits.
