ChanSpy issues a beep when it starts at the beginning of a list of channels to
potentially spy on.  However, if there were no matching channels, it would beep
at you over and over, which is pretty annoying.  Now, it will only beep once in
the case that there are no channels to spy on, but it will still beep again once
it reaches the beginning of the channel list again.

(closes issue #11738, patched by me)
