Expected Behavior

Ingestion should retrieve a set of storages from core, not a list with multiples.

Current Behavior

Given an import job with features sharing stores, the ingestion job will query for the full list of storage ids with duplicates. This will fail the job since the output list of storage specs will be smaller than the list of ids.

Possible Solution

Deduplicating the list of required storage specs will fix this problem (in Specs.java)
