Reaction upper and lower bound aren't copied correctly when calling reaction.copy()

[StevenWijnen]

When you make a hard copy of a reaction both the upper and lower bound aren't copied to the new object given the following error:

` def getUpperBound(self):
"""
Get the value of the reactions upper bound

    """
    try:

      return self.__objref__().getReactionUpperBound(self.id)

E TypeError: 'NoneType' object is not callable`
