[SPARK-23754][Python] Re-raising StopIteration in client code
## What changes were proposed in this pull request?
Make sure that `StopIteration`s raised in users' code do not silently
interrupt processing by spark, but are raised as exceptions to the users.
## How was this patch tested?
Unit tests, making sure that the exceptions are indeed raised.
## License
This is my original work, licensed in the same way as spark
