test/cql-pytest: revert incorrect fix to avoid a warning

In commit 0a71151 I wanted to avoid
a incorrect deprecation warning from the Python driver but fixed it
in an incorrect way. I never noticed the fix was incorrect because
the test was already xfailing, and the incorrect fix just made it
fail differently... In this patch I revert that commit.

With this revert, I am *not* bringing back the spurious warning -
the Python driver bug was already fixed in
datastax/python-driver#1103 - so developers
with a fairly recent version will no longer see the spurious warning.
Both old and new drivers will at least do the correct thing, as
it was before that unfortunate commit.

Fixes scylladb#8752.
