When CircleCI runs my app's test suite, the output is very clouded by excessive prints of this:

To the point that it's difficult to see which test(s) failed or errored at all.

To be clear, this does not show up locally when running the test suite.

Hi there. I'm experiencing the same issue running specs inside a Docker container. Let me know if I can be of any help.

a5dd25c 
Fixes carrierwaveuploader#2493, Closes carrierwaveuploader#2506
Memoizing @versions_to_* is unsafe since versions can change dynamically when conditional version is used.
