Description of problem:

After upgrading to 6.3 with an orphaned redhat repository/product, the redhat repositories page errors with a 404 from candlepin


How reproducible:
Always

Steps to Reproduce:
1.  On Satellite 6.2 (pre upgrade): Import a manifest
2.  Enable at least one repository
3.  Delete the manifest
4.  Upgrade to 6.3
5.  Visit the 'Red Hat Repositories" page

Actual results:
Error, the logs:

2017-07-28 16:03:22 33c833b3 [app] [F] 
 | RestClient::ResourceNotFound (Katello::Resources::Candlepin::Product: 404 Resource Not Found {"displayMessage":"Product with ID '367' could not be found.","requestUuid":"b3991f0f-62a2-4933-bda2-f93e9c4843f4"} (GET /candlepin/owners/Default_Organization/products/367/?include=name&include=attributes.name&include=attributes.value&include=productContent.content.contentUrl&include=productContent.content.label&include=productContent.content.modifiedProductIds&include=productContent.content.type&include=productContent.content.id&include=productContent.content.name)):


Expected results:
page loads fine

Additional info:
Note that deleting the manifest is the easiest way to reproduce this, but it can also happen if some subscription expired, or you've imported/refreshed a new manifest that doesn't contain the product that has a repository enabled (thus is orphaned).
