PROV-757 Fixed indexing issues with SOLR that were resulting in missing indexing. Specifically:
1. Container elements were not being configured correctly in terms of data type. Containers with elements nested > 2 levels down would not have the deep elements indexed at all and another issue prevented any container elements from being configured for indexing.

2. Geocode elements were being improperly emitted causing indexing errors. The errors would invalid entire records resulting in lost indexing.
