redis 4.5.2 breaks bleeding edge unit tests

The nagios test breaks when run using redis v4.5.2 in the wheels unit tests (the "bleeding edge" tests). The error that pops up is pasted below. This may be related to a PR that is in 4.5.2, but I'm not sure. The workaround for now is to pin redis < 4.5.2 (!1116 (merged)), but if this is caused by new redis behavior that isn't a bug then we may need to make changes on our end to use newer versions of redis.
