Error when providing nested input object via variables

[stijnopheide]

This is a minimal case to reproduce (v 0.16.0)

Schema

(def schema
  {:input-objects {:IDObject {:fields {:id {:type '(non-null String)}}}}
   :objects       {:Something  {:fields {:id         {:type '(non-null String)}
                                         :name       {:type 'String}
                                         :otherThing {:type :OtherThing}}}
                   :OtherThing {:fields {:id   {:type '(non-null String)}
                                         :name {:type 'String}}}}
   :mutations     {:CreateSomething
                   {:args {:name {:type 'String}
                           :otherThing {:type :IDObject}}
                    :type :Something}}})

Execute the query by filling in parameters directly

(com.walmartlabs.lacinia/execute (com.walmartlabs.lacinia.schema/compile schema)
                                 "mutation CreateSomething { CreateSomething(name: \"Test\", otherThing: {id: \"ID\"}) {id }}"
                                 nil
                                 nil)
=> {:data #ordered/map([:CreateSomething nil])}

Execute the query by providing variables

(com.walmartlabs.lacinia/execute (com.walmartlabs.lacinia.schema/compile schema)
                                 "mutation CreateSomething($name: String!, $otherThing: IDObject!) { CreateSomething(name: $name, otherThing: $otherThing) {id }}"
                                 {:name "Test"
                                  :otherThing {:id "ID"}}
                                 nil)
=> {:errors [{:message "Sanity check - no option in process-result."}]}

The error happens in com.walmartlabs.lacinia.parser/process-result because there is no matching clause in the cond for (= category :input-object).
