Fix bug - array index error could occur when reaction had different products or reactants between models
Fix bug - array index error could occur when reaction had different products or reactants between models

The stoichiometries corresponding to the different reactants/products would over-write each other in the _stoichiometries array.
This would then be shorter than the list of reactants or products in product_status/reactant_status.
