t2018: be more discerning when checking for expected exit codes
Functions test_dirty_unmergeable() and test_dirty_mergeable()
expect git-diff to exit with the specific code 1. However, rather
than checking for that value explicitly, they instead negate the
exit code. Unfortunately, this negation makes it impossible to
distinguish the expected code from some other unexpected non-zero
code, for instance, from a segmentation fault. Therefore, be more
discerning by checking the exit code explicitly using
test_expect_code().
Furthermore, some callers of those functions want to negate the
result again, and do so with test_must_fail(). However,
test_must_fail() should only be used with git commands. Address
this by introducing a couple new tiny helper functions which test
the exact condition expected (without the unnecessarily confusing
double-negation).
