tests - eo - found eo_signals test is wrong... amazing it passed before

tests - eo - found eo_signals test is wrong... amazing it passed before

so it was listening for cb adds and dels... and or del of any cb
except the cb add/del catcher was done.. it would fail...

but ... the test actually added other cbs than this ... like:

   efl_event_callback_array_priority_add(obj, _eo_signals_callbacks(),
-100, (void *) 1);

a while array of cb's:

{ EV_A_CHANGED, _eo_signals_a_changed_cb },
{ EV_A_CHANGED, _eo_signals_a_changed_cb2 },
{ EV_A_CHANGED, _eo_signals_a_changed_never },
{ EFL_EVENT_DEL, _eo_signals_efl_del_cb });

none of which were _eo_signals_cb_added_deled. i am amazed it passed
before...

now switch its checks to check for itself and then check for anything
BUT itself...
