[Kimchi-devel] [PATCH] Return empty dict when VM doesn't have current snasphot

The current API design is to return an error 404 when a current snapshot doesn't exist on a virtual machine. But it was decided that the best approach is to return an empty structure instead. Return an empty dict instead of raising an error when a VM doesn't have a current snapshot. Also, update the tests accordingly.
