Update tests to check for hostname instead of fqdn

[ajt89]

locust.test.test_log was broken locally for me as test_log was looking at the fqdn instead of hostname. To match this change: #2705

test_logs: commands[0]> python -m unittest -f locust.test.test_log
.F

Hi! A bit more context would be nice :) I'm guessing the tests were failing locally for you for some reason?

Updated with details above, but essentially locust.test.test_log on my local were failing due to this change: #2705

Thx! Guess it was just lucky/unlucky that it worked on github!
