This test issues a reload over the master CLI, but it is totally
possible that the master has not yet finished starting up the master
CLI when the command is issued, resulting in a failure. This was much
more visible on the new master-worker model, but definitely affects the
old one and could be the reason for this test to occasionally fail on
the CI.
