Error thrown on new cljs REPL in fresh project

Nobody has claimed this yet.

Hi,

If I create a luminus project with the +cljs option, as soon as I open clj & cljs REPLs, I get an error thrown (pasted below).

It looks like this is maybe an issue with cljs 1.9.946, as suggested [here](https://groups.google.com/forum/#!topic/clojure/dSrlFNdfIFE) and [here](https://clojurians-log.clojureverse.org/lein-figwheel/2017-10-04.html). Adding an explicit dependency on tools.reader 1.1.0 to the project.clj of the created project eliminates the error. Dropping the cljs version to 1.9.908 also prevents it.

This isn't in my way at all (I was just creating a luminus project to test out another project), just wanted to let you know. Also, despite the error, at least basic functionality (eg `(+ 1 1)`) continues to work in both clj and cljs repl, so I don't know whether it's actually breaking anything.

```1. Unhandled clojure.lang.ExceptionInfo

```

Generate a fresh Luminus project with the +cljs option and open the Clojure and ClojureScript REPLs to reproduce the reader error. Inspect the generated project.clj and the ClojureScript 1.9.946 and tools.reader dependency versions; done means the REPLs start without the reported error while basic expressions continue to work.
