Add a `respond_to_search` test helper for concisely testing that a
controller's index action correctly responds to a search. Usage:
# Tests that `/tags.json?search[name]=touhou` returns the `touhou` tag.
setup { @touhou = create(:tag, name: "touhou") }
should respond_to_search(name: "touhou").with { @touhou }
