testing removing reference from <checkgroup />

under
`highway_yesno_oneway_motorroad_bridge_tunnel_cutting_embankment_lit_toll`

got error in JOSM: unable to parse tagging preset source:
Error is cvc-complex-type.2.4.a: Invalid content was found starting with
element `reference`. One of
`{"http://josm.openstreetmap.de/tagging-preset-1.0":check}` is expected.
(at line 209, column 42)

I expect next error on line 210.
