Removed useless condition from Oracle's NullBooleanField's check constraint.
NULL cannot be compare with standard operators on Oracle, it works only
with IS NULL and IS NOT NULL operators. Therefore 'OR ... IS NULL'
condition in NullBooleanField's check constraint is redundant.
Nullability is checked in a separate constraint.
