git-codereview: fix missing upstream detection

With git 2.4.3, the current tests fail (and it breaks in real use):

$ go test
git rev-parse --abbrev-ref newbranch@{u}
fatal: no upstream configured for branch 'newbranch'

git-codereview: exit status 128
exit status 1
FAIL	golang.org/x/review/git-codereview	0.361s
$

The message changed from "No" to "no". Fix detection.
