Previously the error message when the connection was closed while fetching was "object not found" and was misleading. Now when the packfile size is 0 the error "unable to fetch packfile" is returned.

Does not come with test as I haven't found a way to correctly break the connection while the packfile is being downloaded. Starting git daemon and killing it after some time is not deterministic enough and can be flaky.

Related to src-d/borges#314

You can test it, giving to it an empty io.Reader, no?

I've added a small test that check for ErrEmptyPackfile error with an empty packfile. Still it does not test that a broken connection returns that error.

Keep in mind that this needs to trigger a minor, not patch version (new error returned from existing function).
