out of memory building review app

[dkent600]

This has returned:

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

This is happening in the current dev branch, thus we have no staging builds, and merging dev into any other branch will likely break their review apps too. Like this one:

this is due to #1578
please revert it back @dkent600

@orenyodfat can you please report here what you did here with heroku to workaround this? thanks

I got the slug size back down to 391M without seeing the out-of-memory error by playing with the app config variables:

NODE_ENV staging
NPM_CONFIG_PRODUCTION true

These are set for all 4 staging sites plus all review sites

This continues to happen when we don't use the cheap-module-source-map, for example, this: #1553

Closing, looks like this problem was solved.
