^^^ Here is the problem. Subversion tries to CHECKOUT (DAV HTTP
method) parent of resource when using HTTPv1 protocol, but it should
not. I was able to reproduce this problem locally. As far I see we
don't have test for this case.

As you see Subversion perform DELETE directly, without CHECKOUT when
using HTTPv2 protocol. That's expected behavior.
