[SPARK-8658] [SQL] [FOLLOW-UP] AttributeReference's equals method compares
all the members
Based on the comment of @cloud-fan , update the AttributeReference's
hashCode function by including the hashCode of the other attributes including
name, nullable and qualifiers.
Here, I am not 100% sure if we should include name in the hashCode
calculation, since the original hashCode calculation does not include it.
@marmbrus @cloud-fan Please review if the changes are good.
