nit: should this logging be checked in?

This is the only place where we log all the extensions that are loaded in a
session.

Done.

   bool is_extension_upgrade = false;
   bool is_extension_loaded = false;
   const Extension* old = GetInstalledExtension(extension->id());
   if (old) {
     is_extension_loaded = true;

         extension->version()->CompareTo(*(old->version()));
     is_extension_upgrade = version_compare_result > 0;
     // Other than for unpacked extensions, CrxInstaller should have guaranteed
     // that we aren't downgrading.
