Create a branch for enabling http tests

[donny-dont]

Currently there is a circular dependency between test and http caused by package_resolver. Pub no longer allows a package to depend on itself so dependency_overrides cannot be used to successfully install test within the 0.12.0-dev version of http.

Please create a branch with the following changes so it can be used as an override within http until the dependency here can be loosened.

This looks like #1443, which I thought had been fixed.

@donny-dont, can you open a PR for this branch of package_resolver for now?

[donny-dont]

I swore at one point that you COULD do this but it seems like pub changed to disallow that. Anyways I'll open up a branch on that.

Actually, I just re-tested, and it looks like this works:

dependency_overrides:
  package_resolver: '^1.0.0'

[donny-dont]

@nex3 weird I see that it works as well. Preparing some tests for you to land. I'll do it like that.
