wx: Fix crash when garbage collect event handlers (debugger caused seg fault)

wxStyledTextCtrl had no wrapper class so, because it was not detected
that it had virtual destructors, thus references to it was not cleaned
up on destruction. When a process dies and wx cleans up the event handlers
access was made to the deleted object and caused a seg fault.

Added a testcase which I thought could provoke the bug but didn't.
