Update pytest-mock to 3.5.1

[pyup-bot]

This PR updates pytest-mock from 3.4.0 to 3.5.1.

Changelog

3.5.1

------------------

* Use ``inspect.getattr_static`` instead of resorting to ``object.__getattribute__``
magic. This should better comply with objects which implement a custom descriptor
protocol. Thanks `yesthesoup`_ for the PR (`224`_).

3.5.0

------------------

* Now all patch functions will emit a warning instead of raising a ``ValueError`` when used
as a context-manager. Thanks `iforapsy`_ for the PR (`221`_).

* Additionally, ``mocker.patch.context_manager`` is available when the user intends to mock
a context manager (for example  ``threading.Lock`` object), which will not emit that
warning.
