Fixes nondeterministic test failure: ``` 1) Clover github cache endpoints lists cache entries returns the list of cache entries for the key Failure/Error: expect(response["artifactCaches"].map { [_1["cacheKey"], _1["cacheVersion"]] }).to eq([["k1", "v1"], ["k1", "v2"]]) expected: [["k1", "v1"], ["k1", "v2"]] got: [["k1", "v2"], ["k1", "v1"]] ```
