Intermittent canceled request causing test failure in `afterAll` in CI

[ggetz]

We're seeing an intermittent failure in CI failing due to an error thrown in afterAll with an undefined error.

I'm having trouble reproducing locally, but in test-CI I threw in a few debug statements, and the failure appears to be a canceled request.

Perhaps related to https://github.com/CesiumGS/cesium/issues/3888, but I expect this likely a bad spec.

Just ran into this locally-- It appears to happen in Scene/ArcGisMapServerImageryProvider
