Fix deleting editor controls associated with wxPG properties from within event handler.

Editor controls (and their event handlers) deleted from within wxPG event handler shouldn't by deleted in global idle event handler but only in local wxPG event handler because global idle events can be generated also by calling e.g. wxYield when wxPG is not in the real idle state.

Closes #16617
