2.0.0-dev.41.0 contains broken pub (can not fetch packages)

[jcollins-g]

This issue made it into the pub in that release: dart-lang/pub#1846

Can we add a sanity check to make sure pub can fetch packages? It's quite time consuming to debug, pin my Travis, wait for a non-broken SDK, then unpin again.

[jcollins-g]

To be clear, I'm suggesting a sanity check for this in the SDK prior to building a release version. It should be entirely possible for pub to transiently have even critical failures in development, that's normal, it's just sad to have them escape into the wild. :-(

Great that the base issue is addressed, but I'd like to leave this open to track adding some sort of integration test to prevent this from happening again. In other words, this bug is open because bugs like this can reappear at any time.

Closing -> integration test is covered by #32656
