/**
* A note on this taking Provider<NeoStore> rather than just neo store: This is a workaround until
* the cache is removed. Because the neostore may be restarted while the database is running, and
* because lazy properties keep a reference to the property store, we need a way to resolve the
* property store on demand for properties in the cache. As such, this takes a provider, and uses
* that provider to provide property store references when resolving lazy properties.
