Fixed non working actions for create / extract archives
PanelContextMenu instance created in PanelContextMenu::run now lives long enough so that create / extract archive actions won't be deleted right after PanelContextMenu::run call.
Important note: after this patch I've spotted crash, same as in the bug https://bugs.kde.org/show_bug.cgi?id=443540.
Looks like this crash has been fixed in the KF5 5.89(git).
