Test defonce

[super7ramp]

This closes #225.

ClojureScript CI tests fail:

FAIL in (test-defonce) (clojure/core_test/defonce.cljc:10:11)
defining var only once
expected: (nil? (defonce one 2))
  actual: (not (nil? 2))

ERROR in (test-defonce) (clojure/core_test/defonce.cljc:11:11)
defining var only once
expected: (nil? (defonce one (assert false "should not be evaluated")))
  actual: #object[Error Error: Assert failed: should not be evaluated
false]

FAIL in (test-defonce) (clojure/core_test/defonce.cljc:12:11)
defining var only once
expected: (= 1 one)
  actual: (not (= 1 2))

Can't reproduce, bb test-cljs is ok locally 🤔

Tried to update shadow-cljs (which pulled cljs 1.12.116), got more errors:

Testing clojure.core-test.max

FAIL in (test-max) (clojure/core_test/max.cljc:36:13)
expected: (= 1 (max ##NaN 1))
  actual: (not (= 1 ##NaN))

FAIL in (test-max) (clojure/core_test/max.cljc:39:13)
expected: (= ##Inf (max ##-Inf ##NaN ##Inf))
  actual: (not (= ##Inf ##NaN))

FAIL in (test-max) (clojure/core_test/max.cljc:42:13)
expected: (= "y" (max "x" "y"))
  actual: (not (= "y" "x"))

Testing clojure.core-test.merge

Testing clojure.core-test.min

FAIL in (test-min) (clojure/core_test/min.cljc:36:13)
expected: (= 1 (min ##NaN 1))
  actual: (not (= 1 ##NaN))

FAIL in (test-min) (clojure/core_test/min.cljc:39:13)
expected: (= ##Inf (min ##-Inf ##NaN ##Inf))
  actual: (not (= ##Inf ##NaN))

I get these new errors locally as well (I guess it's #805), on the contrary to defonce ones, which I still don't reproduce 🤔

Might be related to thheller/shadow-cljs#1185.
