Commented-out category generating code in organization controller was
unused and unneeded as categories are now delivered from the API.

Updates tests and cassettes
Merge branch 'master' into kind-category-filter
Removes unused code

Deleted code was part of a branch that used it for pagination, however
it is no longer needed with the merged code from master.
Removes unneeded code

I can't find the combination that returned no results because location
parameter was empty, so removing the code that deletes the empty
parameters. However, ideally empty parameters shouldn't be passed from
the search form at all.
