Adjust list of items for deferred deletion/removal if wxPG property item is actually deleted/removed.

Browse Source 
When property is actually deleted/removed it must be also removed from the respective list of items for deferred deletion/removal in order to avoid crashes when it would be attempted to delete/remove it again at next wxPG idle state.
Because lists of items for deferred operations can be updated at every actual deletion/removal it is necessary to rearrange iteration through these lists in wxPG::OnIdle.

See #16222.
