Properly Implode Nested(Array) Notification Routes To Fix Array To String Conversion Exception

[srinathreddydudi]

When sending an anonymous notification with a string route, The entries are logged successfully. But when using an array of routes, There is an array to string conversion exception in the notification watcher.

// This works well
Notification::route('mail', 'telescope@laravel.com')->notify( new SomeNotification() );

// This throws an array to string conversion exception
Notification::route('mail', ['telescope@laravel.com'])->notify( new SomeNotification() );

I have added a test case which verifies working of the new change with array routes.

This is my first time contributing to an open source project. Please guide me in the right direction if i did not follow any standards.
