[PATCH v4 2/4] test-dump-cache-tree: invalid trees are not errors

[David Turner <dturner@twopensource.com>]

Do not treat known-invalid trees as errors even when their count is
incorrect.  Because git already knows that these trees are invalid,
nothing depends on the count field.

Add a couple of comments.
