Clojurescript rtd-records with more than 20 elements

The following record definition:

```clojure
(:require [active.clojure.cljs.record :as rec :include-macros true])
(rec/define-record-type Rec21 {:rtd-record? true}
make-rec21 rec-21?
[r1 rec-r1
r2 rec-r2
r3 rec-r3
r4 rec-r4
r5 rec-r5
r6 rec-r6
r7 rec-r7
r8 rec-r8
r9 rec-r9
r10 rec-r10
r11 rec-r11
r12 rec-r12
r13 rec-r13
r14 rec-r14
r15 rec-r15
r16 rec-r16
r17 rec-r17
r18 rec-r18
r19 rec-r19
r20 rec-r20
r21 rec-r21])
```

results in an warning:

` Use of undeclared Var [...]/java`

This does not happen with 20 or less elements in the record, or without `{:rtd-record? true}`
