Where several causes of action are asserted in the complaint and each of them would be within the jurisdiction of the court if sued upon separately, the court shall have jurisdiction of the action. In such case judgment may be rendered by the court in excess of $50,000 if such excess result solely because of such joinder. Nothing herein shall be construed to prevent the court from granting judgment in an unlimited amount on a counterclaim.
