fix null pointer in jaeger-spark-dependencies #2327

Is the expectation that any list must not be null, or just references? For example, |

It depends on the consumer, i guess. speaking for see SpanDeserializer.java / ObjectMapper.java. While taking a look at #2295:
I think writing @pavolloffay you're much deeper into this, can you confirm this? If so i'll change *edit* i fixed |

we could avoid some memory allocations by using constants in these cases, like
const emptyReferenceList = []dbmodel.Reference{}
the most impact will be for logs, since it's quite rare to find spans without references or tags.
BTW, I wonder if there is another bug in the translator from OTEL that fails to create a CHILD_OF reference to the parent span ID, which is required in the Jaeger model since we don't store parentSpanID in the database.

Thanks for your feedback, i made changes accordingly.
I don't see where there could be a bug (...or i don't get it 😄 ). The CHILD_OF refs are tested properly as far as i can tell. It either creates a reference or it errors out.

please group all vars at the top of the file (after constants, if any)
var (
emptyReferenceList = []dbmodel.Reference{}
emptyTagList = []dbmodel.KeyValue{}
etc
