[SPARK-16409][SQL] regexp_extract with optional groups causes NPE
## What changes were proposed in this pull request?
regexp_extract actually returns null when it shouldn't when a regex matches but the requested optional group did not. This makes it return an empty string, as apparently designed.
## How was this patch tested?
Additional unit test
