Can't empty a Record

[NoahTheDuke]

When comparing two objects where the first is a Record and the second is a sequence, remove will execute the :else of the cond, calling empty on the record, which will throw a java.lang.UnsupportedOperationException error.

user=> (defrecord t [value])
user.t
user=> (def t1 (t. 1))
#'user/t1
user=> (require '[differ.core :as differ])
