[SPARK-4041][SQL] Attributes names in table scan should converted to lowercase when compare with relation attributes
In ```MetastoreRelation``` the attributes name is lowercase because of hive using lowercase for fields name, so we should convert attributes name in table scan lowercase in ```indexWhere(_.name == a.name)```.
```neededColumnIDs``` may be not correct if not convert to lowercase.
