An assertion `server_state_.rollback_mode() == wsrep::server_state::rm_async` fired in before_command() when - thread-handling was set to pool-of-threads and - a BF abort happened between client session calls to wait_rollback_complete_and_acquire_ownership() and before_command(). This commit introduces a test case to reproduce the crash and updates wsrep-lib submodule to fixed version.
