[Android WebAPK] Fix First Run showing twice for Maps Go

This CL fixes a bug introduced by
http://crrev.com/95ad83cedf394b9b37a8b3ab151116918b8f64ec where the
first run experience would show twice for Maps Go -> the lightweight
FRE launched by WebappLauncherActivity and the full FRE launched by
AsyncInitializationActivity. This CL is a partial revert of the CL.

This CL is simple so that it can be potentially merged back. The
"proper" fix is at
https://chromium-review.googlesource.com/c/chromium/src/+/1478460
