Dandelion Mané a0b754bb43 upgrade to webpack 4
Now that babel is upgraded, upgrading webpack was pretty
straightforward.

- We take advantage of the new `mode` config option, and no longer need
to manually set up Uglify plugin
- Uglifyjs is back, I checked the prod build output: it's very ugly
- I updated the RemoveBuildDirectoryPlugin per instructions, and
verified it still works.
- I verified that of `yarn backend`, `yarn build`, and `yarn start` all
still work as expected.
