Clean up blob diff path

Browse Source 
Previously when diffing blobs, the diff code just ran with a NULL
repository object. Of course, that's not necessary and the test
for a NULL repo was confusing. This makes the blob diff run with
the repo that contains the blobs and clarifies the test that it
is possible to be diffing data where the path is unknown.
