Fix Tox test of dex and oidc client

The dbapi.address_get_by_name function is returning a list now.  Zuul
log says "AttributeError: 'list' object has no attribute 'address'"

Add some debug and a length assertion, but use the first address in the
list.

Test Plan:
PASS  Zuul's tox execution passes with new logs
