ci/travis.py: also wait if in "created" state

Apparently they added this state; example: https://gitlab.labs.nic.cz/knot/knot-resolver/-/jobs/275512

merged

mentioned in commit ac789eba

I wonder... why is even continue used there? Won't that lead to repeating requests.get() too fast due to skipping the time.sleep() part? (i.e. I'd expect pass instead of continue)

You're right. I'll add it to my branch of nitpick fixes.
