No action or proceeding to which any municipality merged into the city and county of Denver is a party or in which it is in any way interested shall abate by reason of such merger, but the same shall survive and be prosecuted to a conclusion under its title as borne by it at the time of such merger; and any judgment or decree entered therein shall be enforceable by or against the city and county of Denver to the full extent of the interest or liability of the said municipality so merged, the same as if said city and county of Denver were expressly made a party thereto. No right or cause of action by or against any such municipality so merged shall be lost or extinguished by reason of such merger, and the same shall be thereafter enforced and prosecuted by or against the city and county of Denver.
