SIDARTHE Template model contains lambda parameter, but SIDARTHE modeling.Model drops it

I believe at that stage it's called XXlambdaXX. The export into AMR will reintroduce the expected lambda.

>>> set(template_model.parameters.keys()) - set(model.parameters.keys())
{'lambda'},

But

>>> set(model.parameters.keys()) - set(template_model.parameters.keys())
{(('Infected', ('identity', 'ido:0000511')),
   ('Healed', ('identity', 'ido:0000592')),
   'NaturalConversion',
   'rate')})

and the value of this parameter is None

>>> model.parameters[(('Infected', ('identity', 'ido:0000511')),
   ('Healed', ('identity', 'ido:0000592')),
   'NaturalConversion',
   'rate')].value is None
True
