Stop using pytest-randomly in tests (#112)

This removes the `pytest-randomly` Pytest plugin, as it doesn't play
nice with `pytest-xdist`.

`pytest-randomly` (among other things) sets the random seed in the
beginning of the tests to the current datetime. `pytest-xdist` runs the
tests in parallel in multiple runners. When you use these two together,
it happens that all of the runners have the same random seed, so if you
e.g. [generate random resource
names](https://github.com/apify/apify-client-python/blob/13c029e82731138cf67912fe6b375ab61846d4c5/tests/integration/test_request_queue.py#L7-L12),
all runners will generate the same ones, leading to conflicts.

The other feature of `pytest-randomly`, running the tests in random
order to ensure that the tests are not passing just because of some side
effects caused by running in a specific order, does not work with
`pytest-xdist` at all, so there are zero benefits of using
`pytest-randomly` at all.
