Opening email with file attachment causes app crash on Android 8

File access has been changed on Android 8, so using the current plugin implementation to attach a file to an email causing a crash on Android 8:

To reproduce, just create a Cordova test project and run the example code on deviceready in Android 8 emulator/device:

cordova.plugins.email.open({
    attachments: [
        'file://img/logo.png', //=> assets/www/img/logo.png (Android)
        'file://css/index.css' //=> www/css/index.css (iOS)
    ]
});

The same code runs fine on Android 7.1.1 and below.

Seems there is a potential solution in this SO post.

@dpa99c Could you please let me know if it's working by installing the plugin from master?

[dpa99c]

@katzer Yes, this fixes it. Tested the master branch with Android 8.0 and it now works fine.
Thanks for the quick turnaround time.
