fix auto completion in default empty script of GUI editor (bug #60689) * file-editor.cc (file_editor): initialize new data member m_editor_ready storing whether the editor is ready after startup; (empty_script): set ready flag at startup, return on non-startup calls if editor still not ready; (handle_visibility): just return if editor is not yet ready; * file-editor.h new data member m_editor_ready
