[PATCH] test: swap order of arguments of test_expect_equal

[David Bremner]

For some reason (probably inherited from git), the order arguments for
test_expect_equal was "$output $expected"; this again matters when
generating diffs.
---

I'm less sure about this one so I didn't go through and update all of
the tests.  The existing use of test_expect_equal is mostly "$output"
"$expected", which is natural enough, except that it's the opposite of
the convention for test_expect_equal_file that I thought was obvious
(I guess the latter motivated by the arguments to diff).
