Use GitHub source to get tests; omit tox

The PyPi tarball doesn't have any tests in it, so this package isn't
really testing anything. Switch the source to the GitHub release to
download tests as part of the source.

Also use pytest for tests in place of tox since the tests work the same
way and we avoid tox dependencies going back into EPEL.

Add an import check in %check as well.
