Prevent repeated identicial queries to repository #46

Closed rwd closed 6 years ago

rwd commented 6 years ago

Observed when using rdf-mongo for the repository adapter, Spira::Persistence#reload seems to result in multiple identical queries to the repository. (Once for each property on the model class?)

This change:

exits early if the query response is nil
otherwise reads all the statements from the query response once, preventing the duplicate queries to the repository
