Problem/Motivation
After #1953800: Make the database connection serializable Drupal 8-x.dev fails to install if SQLite chosen as database system. The install fails with "The server reports the following message: The service definition "request" does not exist" after SQLite chosen as database for install in database selection form. Fixing 2 code errors in core/lib/Drupal/Core/Database/Driver/sqlite/Connection.php allows the install to progress further. Cannot move forward on #1998366: Install with SQLite fail - Failed to connect to your database server. until this is in.
