(Standard_OfVisitor): After concatenating to automata, and before
erasing the obsolete initial state of the RHS, do not explicitly
erase the transition leaving that initial state.  This is useless
because del_state() already does the work.  This was bogus because
del_transition invalidates the delta_iterator in the listg
implementation.
