Subject: gnu: python-celery: Update to 4.2.1.

This is an attempt to get the package building after the update to Python
3.7. I'm not sure this totally works, as the tests detect an incompatibility
with Python 3.7 due to use of "async". But with the tests disabled, you can at
least import the celery module, which is a start.

* gnu/packages/python.scm (python-celery): Update to 4.2.1.
[arguments]: Switch to py.test, from nose, disable the tests and loosen the
requirements on pytest.
[native-inputs]: Remove python-nose, add python-pytest and python-case.
[home-page]: Change from HTTP to HTTPS.
