Bring app to foreground after authentication (#85)

* Add onLoginSuccess implementation to CustomTabURLOpener

This will bring the app's main activity to foreground
after successful authentication

* Check isOpened is set to true on 'onLoginSuccess' callback

* Update submodule reference and URL to forked repo

Once the forked repo's PR is approved, it will be
changed back to the original URL

* Update submodule reference and URL back to main
