This ctor just created unusable wxTimerEvent objects (all of the methods
specific to this class would just crash if called on them) and doesn't
seem to be useful at all.
It was added in e47859daeb apparently only
in order to allow using wxIMPLEMENT_DYNAMIC_CLASS() instead of the
previously used wxIMPLEMENT_ABSTRACT_CLASS() for wxTimerEvent, but there
doesn't seem to be any reason to prefer macro over another, and there
are good reasons to not allow creating objects in an invalid state.
The only place where we relied on having default ctor for this event was
in wxEvent::Clone() unit test, so update it to handle wxTimerEvent
specially now that this ctor doesn't exist any longer.
