toolbar: Fix crash on more_item when shrink mode is set with no item.

Toolbar creates a more_item when shrink mode is
ELM_TOOLBAR_SHRINK_EXPAND.
If select mode is ELM_OBJECT_SELECT_MODE_ALWAYS and there is no item
appended, then toolbar sets a selection on a newly created item.
In this case, sd->more_item is referenced before the new more_item is
assigned to sd->more_item.

@fix
