Revert of Use apps::AppEventRouter to launch app_shell apps...

Revert of Use apps::AppEventRouter to launch app_shell apps (https://codereview.chromium.org/219513005/)

Reason for revert:
This creates an unwanted dependency from app_shell back onto apps (we're moving it to depend only on extensions to keep the binary small).


Original issue's description:
> Use apps::AppEventRouter to launch app_shell apps
> 
> Now that the app_runtime API has moved to //apps we can eliminate a small
> amount of code duplication in app_shell.

> BUG=357818
