Description
When a user configures a Rya Client to use Precomputed Joins for querying, it also adds the PrecomputedJoinIndexer to the list of additional indices. This should not be the case as the PrecomputedJoinIndexer is used to incrementally update PCJs as data is ingested, while enabling PCJs is a query client feature that can be used to boost query performance. Given the different roles of these two features, their configuration should be decoupled.
