[SPARK-11633] [SQL] HiveContext's Case Insensitivity in Self-Join Handling
When handling self joins, the implementation did not consider the case
insensitivity of HiveContext. It could cause an exception as shown in the JIRA:
```
TreeNodeException: Failed to copy node.
```
The fix is low risk. It avoids unnecessary attribute replacement. It should
not affect the existing behavior of self joins. Also added the test case to
cover this case.
