hyprland/ipc: swap windowTitle and windowClass in openwindow handler

The openwindow event format is ADDRESS,WORKSPACE,CLASS,TITLE but the
handler was parsing args.at(2) as title and args.at(3) as class,
which is reversed.

This caused windows to display their class name instead of their
actual title when the openwindow event arrived after windowtitlev2,
since updateInitial would overwrite the correct title with the class.
