viewing the UI repositories list will trigger s3 blobstore metrics retrieval even if that blobstore is not used

Create an S3 blobstore, but do not configure any repositories to use it.
Refresh or load the repository list in the UI.
Nexus will make 2 HTTP requests per s3 blobstore / per repository even though none of the repositories use that s3 blobstore and none of the UI seemingly uses the information The requests are related to reading the S3 blobstore metrics file.

This is the request that ultimately triggers the outbound requests:

2019-03-27 16:37:18,831-0300 DEBUG [qtp458657902-218] admin com.softwarementors.extjs.djn.router.processor.standard.json.JsonRequestProcessor - Request data (JSON)=>

{"action":"coreui_Blobstore","method":"read","data":null,"type":"rpc","tid":63}

Expected

Nexus should avoid making potentially latent outbound requests for information that is not even rendered in a UI view or has anything to do with that data displayed to a user.
