Namespaced keywords broken when referenced outside of the current namespace

For example, this works:

```
cljs.user=> (load-file "../test/cljs/cljs/quick.cljs")
cljs.user=> (in-ns 'cljs.test.quick-tests)
cljs.user=> (run-tests)
```

However, this does not:

```
cljs.user=> (load-file "../test/cljs/cljs/quick.cljs")
cljs.user=> (cljs.test.quick-tests/run-tests)
#<Error: Assert failed: (= *ns-sym* (symbol (namespace :G__1/foo)))> at line 1
```
