Make message from wxApp::OnUnhandledException() more clear

This message now appears even in the (default) release builds as __WXDEBUG__
is always defined, so it needs to be at least somewhat understandable by
normal users, even if it remains primarily targeted at the developers.

Also remove __WXDEBUG__ checks in this function, this is a left-over from the
pre-3.0 debug mode.
