Fix missing value of FieldSort for unsigned_long

[bugmakerrrrrr]

Description

Two changes here:

1. Fixes parsing numeric missing value of unsigned long type. When we pass a numeric missing value like 4 to unsigned long field sort, the ClassCastException will be thrown(class java.lang.Integer cannot be cast to class java.math.BigInteger ).
2. Requires the missing value of unsigned long type must not be negative.
