“Wrong number of arguments: (4 . 4), 0” appears again!

Tested on:

```
macOS Catalina 10.15
elpa: 26.1
Cider version: 0.22.0 and 20191103.1528
flycheck-clojure version: 20190611.2351
flycheck version: 20191028.2247
```

Opening cider-jack-in when in a clj file of a clj project, it always pop up errors when typing any character :

```
Wrong number of arguments: (4 . 4), 0
Error from syntax checker clojure-cider-eastwood: Done with no errors
```

Using [purcell's config](https://github.com/purcell/emacs.d).

And tested with:

```
;; Local Variables:
;; indent-tabs-mode: nil
;; flycheck-disabled-checker: (clojure-cider-eastwood)
;; End:
```
