fix: set original_uuid in ErrorObject when batch send raises exception

[rayensamali]

Fixes #942

When an unexpected exception is raised during batch send, ErrorObject was
created without original_uuid, leaving it as None even when the source
object had a UUID. This fix passes original_uuid=obj.uuid in the exception
handler in base.py, consistent with how it is set in grpc_batch.py.
Added unit tests in test/collection/test_batch.py to verify original_uuid is preserved.
