Guards against null-pointer during schema validation
This edit fixes a null-pointer exception which we encountered during
testing. Truncated stack trace:
```
[2016-04-04 18:27:03,667] ERROR CRITICAL: Failed to serialize offset data,
making it impossible to commit offsets under namespace
test-fileconnector-source. This likely won't recover unless the unserializable
partition or offset information is overwritten.
