tests fail on 0.33.0 because of missing utils.py in the released tarball

[landryb]

running tests from 0.33 release fail:

_________________ ERROR collecting tests/test_wps_request2.py __________________

the source tarball on pypi doesnt contain tests/utils.py

[landryb]

manually fetching the missing file helps, but since the tarball doesn't contain the test resources either, most of the tests fail anyway. cant remember if thats a regression from the move to the build module in #969

Looking at the older tarballs, the test folder wasn't previously included:

https://pypi.org/project/OWSLib/0.31.0/#files

https://files.pythonhosted.org/packages/7a/f6/d739b48f3ae0067996fd3c2e11e066c74cd5158e363dc672529385ccca34/OWSLib-0.31.0.tar.gz

As the tarball doesn't contain the sample data files either (so nearly all tests will fail) I don't think the tests should be included in the tarball at all.

There are also deprecation errors related to the test commands in setup.py which can also probably be removed:

<string>:12: SetuptoolsDeprecationWarning: The test command is disabled and references to it are deprecated.
!!

        ********************************************************************************
        Please remove any references to `setuptools.command.test` in all supported versions of the affected package.

        This deprecation is overdue, please update your project and remove deprecated
        calls to avoid build errors in the future.
        ********************************************************************************

Fixed with #986
