sureshthalamati e42724b12b [SPARK-13167][SQL] Include rows with null values for partition column when reading from JDBC datasources.
Rows with null values in partition column are not included in the results because none of the partition
where clause specify is null predicate on the partition column. This fix adds is null predicate on the partition column  to the first JDBC partition where clause.

Example:
JDBCPartition(THEID < 1 or THEID is null, 0),JDBCPartition(THEID >= 1 AND THEID < 2,1),
JDBCPartition(THEID >= 2, 2)
