[PATCH]: org-columns does not respect global-visual-line-mode for long text within headlines

I've done some more research on 
https://orgmode.org/list/875z02si3g.fsf@nicolasgoaziou.fr/, and I 
believe the issue is that `org-columns' is setting `truncate-lines' as 
t, while `global-visual-line-mode' is expecting it to be set to nil. The 
interaction between the two causes the wrapping to not occur. 
`org-columns; also cleans up after itself and replaces truncate-lines 
with the original value, which is why the problem only occurs when 
`org-columns' is enabled it.

The attached patch ensures the behaviour is correct when 
`global-visual-line-mode' is enabled and that there are no behaviour 
changes when it has not already been enabled.

Subject: [PATCH] lisp/org-colview.el: Update org-columns to respect
 global-visual-line-mode

* lisp/org-colview.el (org-columns): Prevent enabling truncate-lines
when global-visual-line-mode is also enabled

Fixing a bug where org-column overlays were disabling wrapping of
lines when global-visual-line-mode was already activated, and so
therefore expectation was that the lines would continue wrapping. This
is because org-columns was setting truncate-lines to t, when
global-visual-line-mode requires it to be set to nil. The interaction
between the two caused the wrapping not to occur.
