Remove console logs (release)

[infoproducts]

I do it like this:

app/config/uglifyjs.config.js

let defaultConfig = require('@ionic/app-scripts/config/uglifyjs.config');

module.exports = Object.assign({}, defaultConfig, {
	compress: Object.assign({}, defaultConfig.compress, {
		drop_console: true,
		drop_debugger: true
	})
});

app/package.json

{
...
    "config": {
        "ionic_uglifyjs": "./config/uglifyjs.config.js"
    },
...
}
