If a refspec addresses an upstream branch which commit happens to be
local already, checkout will not properly replicate that into a local
branch. Extend contains_refspec_cmd so that it does not falsely report
the remotes/origin/ ref as locally available and rather triggers its
fetching.
The related test case was papering over this issue so far. Adjust it
accordingly.
