cover: handle undefined module when analysing to file
It is possible that not just the source but even the beam of a module is not available when calling analyse_to_file. For example when coverdata is imported from an old file and since then a module was removed. Before this fix cover:analyse_to_file/3 could possibly never return because of a helper process crashed with error:undef and never reply to the caller. At the same time link the helper process to cover_server so any further error won't let the caller waiting indefinitely.
