Renaming local doesn't rename in every .cljc branch

Given this code in a `.cljc` file:

``` clojure
(let [instance-expr 1
instance-expr instance-expr]
#?(:clj [instance-expr]
:cljs [instance-expr]))
```

when renaming the second `instance-expr` in the `let` form, only the `:clj` branch local is renamed, not the `:cljs` one.
