Make Neo4jModelParser handle queries on fields that are ignored in Neo4j loading but the data exists elsewhere

[sammyjava]

A prime example:

Task -
./gradlew modelParser -PArgs=src/main/resources/preview-genomic_model-neo4j.xml,Gene.chromosome
Output - 
Gene.chromosome --> chromosome

In fact, SequenceFeature.chromosome is ignored in Neo4j loading since the chromosome is pointed to via chromosomeLocation:

Gene.chromosome -> Gene.chromosomeLocation.locatedOn -> (:Gene)-[:LOCATED_ON]->(:BioEntity)

Wrangle Neo4jParser so that it indicates all of this somehow.
