Modify approach to use 'getstream' instead of 'stream-chat'

Note: the addition of `(window as any).global = window;` to the polyfills.ts page is part of a solution for an "UncaughtReference error: global is undefined" error I was getting after importing 'getstream' to chat-service.ts. See comment section of angular/angular-cli#9827.
