Before, we were running `test_must_fail do_checkout`. However,
`test_must_fail` should only be used on git commands. Teach
do_checkout() to accept `!` as a potential first argument which will
prepend `test_must_fail` to the enclosed git command and skips the
remainder of the function.
This increases the granularity of the test as, instead of blindly
checking that do_checkout() failed, we check that only the specific
expected invocation of git fails.
