In no case shall the want of preparation for trial of one claim delay the trial in respect to others, but trial shall be had upon issues between such parties as are prepared without references to issue between other parties; and when one creditor shall have obtained a judgment for the amount due, the court may order a sale of the premises on which the lien operates, or a part thereof, so as to satisfy the judgment: Provided, That the court may, for good cause shown, delay making any order for sale or distribution until the rights of all parties in interest are ascertained and settled by the court.
