While it is not guaranteed in general that destroying a window from an
event handler for an event originating from this window itself works, it
did use to work in the case of wxToolBar and its event handlers. However
this stopped working since faffaaae29
as
it added a test using the now deleted object member fields after the
call to the event handler.
To fix this regression without reintroducing the bug fixed by that
commit (see #16762), add an ugly way to check if the toolbar is still
alive after a call to its event handler and do it explicitly after
OnLeftClick() returns.
Closes #17732.
