Update pytest-mock to 3.0.0

[pyup-bot]

This PR updates pytest-mock from 1.13.0 to 3.0.0.

Changelog

3.0.0

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

* Python 2.7 and 3.4 are no longer supported. Users using ``pip 9`` or later will install
a compatible version automatically.

* ``mocker.spy`` now also works with ``async def`` functions (`179`_). Thanks `frankie567`_ for the PR!

2.0.0

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

Breaking Changes
++++++++++++++++

* ``mocker.spy`` attributes for tracking returned values and raised exceptions of its spied functions
are now called ``spy_return`` and ``spy_exception``, instead of reusing the existing
``MagicMock`` attributes ``return_value`` and ``side_effect``.

Version ``1.13`` introduced a serious regression: after a spied function using ``mocker.spy``
raises an exception, further calls to the spy will not call the spied function,
always raising the first exception instead: assigning to ``side_effect`` causes
``unittest.mock`` to behave this way (`175`_).

* The deprecated ``mock`` alias to the ``mocker`` fixture has finally been removed.
