Summary:
`DrydockAuthorizationSearchEngine` was being used solely to display authorizations for a specific blueprint from the web UI and consequently expected that callers set a specific blueprint before performing a query. Here we check to see if a blueprint has been set in cases where the engine could be operating from either Conduit or the web.
Ref T11694
Test Plan:
- called the API method from the console
- approved an authorization
- followed the "view all" link from a blueprint page
