Temporarily skip the double AuTest to unblock PRs

There is an issue opened to track the intermittent failures in the
double.test.py, see #7946.

In the meantime, concurrently with that being actively investigated,
this PR skips the double.test.py. This is a temporary workaround to
remove the friction this test is adding to our PR process. This patch
should not remain in place for more than a few days.
