patch 9.1.1599: :bnext doesn't go to unlisted help buffers

Browse Source 
Problem:  :bnext doesn't go to unlisted help buffers when cycling
          through help buffers (after 9.1.0557).
Solution: Don't check if a help buffer is listed (zeertzjq).

From <https://github.com/vim/vim/issues/4478#issuecomment-498831057>:

> I think we should fix that, since once you get to a non-help buffer
> all unlisted buffers are skipped, thus you won't encounter another
> help buffer.

This implies that cycling through help buffers should work even if help
buffers are unlisted. Otherwise this part of :bnext isn't really useful,
as :h makes help buffers unlisted by default.
