test(promql): fold range_presence_null into null_samples
#9104 landed its own NULL-sample case whose data is the same series this one already used: one host with interior NULLs, one host with nothing but NULLs. Keeping both means two files asserting the same semantics on the same rows. The merged case keeps every query from both, so the presence functions still cover the trailing-NULL window, the count of two, the empty left-open window at t=7, and the all-NULL windows.
