Deleting the old code handling Alt+ mouse left click to trigger node Autocomplete

Bind NodeAutoComplete to double left click here using Grid.InputBindings since Grid does not expose double left click event directly

I will wait for the self serve to finish. I think the unit tests were using view command directly so we may be fine there but good points!
