fix(test): don't expect specific status code in queue shutdown test (#…

…11606) (#11611)

konghq.com:80 no longer responds with 301 to POST requests, but as
we're not interested in the specific status code anyway, remove it
from the expected string.  We only need to make sure that an attempt
was made to contact the log server (konghq.com).
