The segfault happened executing `AlterTableInternal` for setting the REPLICA IDENTITY during chunk creation (introduced by #5512) that is dispatched by a trigger invoked by a DDL statement. Fixed it by using our internal `ts_alter_table_with_event_trigger` handler function to setup the event trigger context. Fixes #7406
