Load the collection in the controller
Interfacing with external services like solr ought to be done in the controller rather than in the view
Does this PR have implications for how other components are loading page_location ? They should continue to load as a helper as in:

@marlo-longley no, I don't think anything is changed about it. Its still in the helper context.
