nexus-cli making extra anonymous request before sending credentialed request

[gmanfunky]

Below you can see a usual nexus-cli behavior from a web-server log perspective.

Note the second request returns a 307 redirect, leading to the third request, which is sent without the configured credentials resulting in a 401 if anonymous access is disabled.

Expected behavior: Just go ahead and send the artifact request with basic authentication the first time. No need to wait for a "challenge"

When configured with credentials, I think we are assuming basic authentication in the case of maven repos.
