1. bb dev on 0060c6a
2. start nrepl server
3. send completion request
   there is an error

I am testing this by connecting with cider and evaling this form:

(cider-nrepl-send-sync-request
 '("op" "complete"
   "prefix"
   "laod-"
   "ns" "example")
 (cider-current-connection))```

I can also repro this on latest master via:

[benj@benj-pc nbb] 1 $ bb --main nbb-nrepl-tests
