We recently introduced a regression in cloning repositories onto
case-insensitive file systems where the repository contains multiple
files differing only in case. In such a case, we would segfault. This
segfault has already been fixed (repository: pre-initialize hash algo
pointer), but it's not the first time similar problems have arisen.
Introduce a test to catch this case and ensure the behavior does not
regress.

I've verified that the test does fail without the patch on a vfat file
system. However, many other tests also fail on a vfat file system on
Linux, so unfortunately that doesn't look like a viable testing strategy
going forward.
I didn't include an object ID for the commit referenced simply because I
didn't see one yet and I didn't want to insert a local one that wouldn't
work for anyone else.
