[PATCH 1/2] t1506: more test for @{upstream} syntax

[Junio C Hamano <gitster@pobox.com>]

This adds a few more tests that exercises @{upstream} syntax by commands
that operate differently when they are given branch name as opposed to a
refname (i.e. where "master" and "refs/heads/master" makes a difference).
