test(resolver): write the globals fixture the way neovim does

Browse Source 
neovim's globals.h uses `#pragma once`. With an include guard these declarations get no Variable
node, so the rows were testing the wrong thing. `curwin->w_cursor = v` has no usage row for
curwin, so the read of the global is checked at a reading site.
