The breakage is because of current_ref always being null.  The old
code would allow locking a non-existant ref in this case while the
new code was failing.  A simple change such as the following should

Fix fetch when using reflog.

Previously fetch was permitted to create refs if they did not exist;
this only worked as current_ref was always NULL and thus never
would get compared against the existing ref.
