[NSE-1171] Throw RuntimeException when reading duplicate fields in case-insensitive mode #1173

What changes were proposed in this pull request?

We didn't cover the corner case when reading duplicate fields in case-insensitive mode. If there is one more field matched, we just return the first field that matched. However in vanilla spark, it will throw RuntimeException in theses cases.

How was this patch tested?

unit tests
