We were missing a test that would exercise trx_free_prepared() with innodb_fast_shutdown=0. Add a test. Note: if shutdown hangs due to the XA PREPARE transactions, in MariaDB 10.2 the test would unfortunately pass, but take 2*60 seconds longer, because of two shutdown_server statements timing out after 60 seconds. Starting with MariaDB 10.3, the hung server would be killed with SIGABRT, and the test could fail thanks to a backtrace message.
