bug#38384: (next|previous)-buffer silent about not switching

In some circumstances, next-buffer and previous-buffer do not have any buffer to switch to, and in that case they silently do nothing.  (Strictly speaking, they call switch-to-(next|prev)-buffer, which do nothing and return nil).

I think they should throw a user-error, to inform the user about the situation.
