Correctly Support many through

[zeisler]

has_many :decision_mortgages
has_many :credit_liabilities, through: :decision_mortgages

ActiveMocker treats credit_liabilities as an association on the parent model and ignores the through.

The work around is

Model.new(credit_liabilities: credit_liabilities)

It should work like:

Model.new(decision_mortgages: [DecisionMortgage.new(credit_liability: CreditLiability.create)])
