combining with montiapm breaks HCP when using --production

[namenotrequired]

This bug happens only when running meteor --production but I'm not sure it happens on actual build/deploy. I stumbled upon it while looking for another bug. But I figured you'd want to know

Steps to reproduce:

$ meteor create reproduce --blaze
$ cd reproduce
$ meteor remove standard-minifier-js
$ meteor add zodern:standard-minifier-js
$ meteor add montiapm:agent
$ meteor --production

Or replace montiapm:agent with montiapm:profiler for the same result

• Open localhost:3000 in a browser -> see the basic click app
• Edit client/main.js e.g. to add a console.log() statement somewhere (but make sure it's a new hash)
• wait for the browser to refresh

Result: the browser refreshes to a blank page, with an error in the console that it failed to fetch the javascript

I've seen this issue too. The build on disk seems correct, but the running app returns a 404 for the new js file.
