[SPARK-16936] [SQL] Case Sensitivity Support for Refresh Temp Table
### What changes were proposed in this pull request?
Currently, the `refreshTable` API is always case sensitive.
When users use the view name without the exact case match, the API silently
ignores the call. Users might expect the command has been successfully
completed. However, when users run the subsequent SQL commands, they might
still get the exception, like
```
Job aborted due to stage failure:
Task 1 in stage 4.0 failed 1 times, most recent failure: Lost task 1.0 in
stage 4.0 (TID 7, localhost):
java.io.FileNotFoundException:

```
