Don't remove debug statement in minified

[kickinbahk]

Uglify removes the debug statement when it is used

https://stackoverflow.com/questions/55671922/does-the-debugger-command-get-removed-after-a-minify

To have it work it needs the compress config option passed:

.pipe(uglify({ mangle: { reserved: ["jQuery", "$"], keep_fnames: true }, compress: {
      drop_debugger: false,
    } }))

Might be worth a broader thought of if we need to add a production vs development script to change which config settings are passed to uglify.
