Misc #11131: Unexpected splatting of empty kwargs

def foo(); :ok end
foo(*[]) #=> :ok
foo(**{}) #=> ArgumentError: wrong number of arguments (1 for 0)
foo(*[], **{}) #=> ArgumentError: wrong number of arguments (1 for 0)

I was expecting kwargs splatting to work the same as args splatting and be ignored when an empty container is passed.
