fix(build): Removed browser entry from package.json

[deini]

Fix for #156:

So there were 2 issues, first the replace plugin has to go before other plugins such as commonjs.

Also we had browser in package.json which Webpack will default to when resolving modules, so instead of resolving to lib/ng-redux.js (main) or es/ng-redux.js (module) it was resolving to dist/ng-redux.js which we build with env set to development

ng-redux/package.json

Line 20 in e1973f7

"build:umd": "cross-env NODE_ENV=development rollup -c -o dist/ng-redux.js",
