BigDecimal.java (BigDecimal(String)): Always set scale to zero when there is an exponent and the significant is zero.

       * java/math/BigDecimal.java (BigDecimal(String)): Always set scale to
       zero when there is an exponent and the significant is zero.
       (divide): Always set scale to newScale even in special ZERO case.
