Do not add a beforeunload event listener when running inside NodeJS

This solves this problem:

SHADOW import error /home/asp/projects/xxx/.shadow-cljs/builds/server/dev/out/cljs-runtime/taoensso.sente.js

/home/asp/projects/xxx/target/private/js/server.js:64
  /* ignore this, look at stacktrace */ fn.call(global, require, module, __filename, __dirname);
                                           ^

@theasp Thanks for this Andrew! Any urgency from your end for a new release, or could it wait a few weeks while I finish up some other stuff?

Hi Peter,

No urgency on my part, take your time. I didn't even notice for over a year!

Merging manually now, thanks again Andrew!
