Electron 4 support

[DreamitMauri]

Since upgrading to Electron 4.0.1 from Electron 2.0.14 I receive these errors:

npm ERR! code ELIFECYCLE
npm ERR! errno 3221225477

Here's my code:

    import { setup as setupPushReceiver } from 'electron-push-receiver';

    // Create the browser window.
    browserWindow = new BrowserWindow({
        x: 0,
        y: 0,
        width,
        height,
        frame: serve,
        backgroundColor: '#333333',
        icon: `${__dirname}/src/assets/icons/icon.png`,
        webPreferences: {
            // disable CORS
            webSecurity: false
        }
    });

    // Set up push notification receiver
    try {
        setupPushReceiver(browserWindow.webContents);
    } catch (e) {
        logError(e);
    }

There is no exception from setupPushReceiver, the app just crashes.

Also tested with Electron 3.1.0. Same issue.

I've done some more digging on this.

I believe the issue is with push-receiver (https://github.com/MatthieuLemoine/push-receiver) and not this package. I have created an issue there: MatthieuLemoine/push-receiver#23
