[PATCH] pre-commit hook tests: don't leave "actual" nonexisting on failure

Start by creating an "actual" file in a core.hooksPath test that has
the hook echoing to the "actual" file.

We later test_cmp that file to see what hooks were run. If we fail to
run our hook(s) we'll have an empty list of hooks for the test_cmp
instead of a nonexisting file. For the logic of this test that makes more sense.

See 867ad08a261 (hooks: allow customizing where the hook directory is,
2016-05-04) for the commit that added these tests.
