Depends on:
NativeScript/android#923
NativeScript/NativeScript#5257

BREAKING CHANGES:

`uglifyMangleExcludes` is no longer exported from the
nativescript-dev-webpack plugin and shouldn't be used in the webpack
configuration.

Before:
```
// webpack.config.js
// ...
uglifyOptions: {
    mangle: { reserved: nsWebpack.uglifyMangleExcludes },
    // ...
}

```

After:
```
// webpack.config.js
// ...
uglifyOptions: {
    // ...
}

```
