don't use axiomatization proposed in rsc-ontologies#27 on "oxidative cleavage" and alkene oxidative cleavage

reason:'has occurrent part' some 'breaking of covalent bond' is too inspecific as it doesn't restrict it to the reactive centre, which would be actually needed in this case. thus keeping both parents
