    wayland: Don't abort when preparing the source if connection is lost
    
    Aborting the application makes it look like an application bug, when
    it is the expected thing to do when the Wayland display server goes
    way. eg., when the user logs out. The log level is also demoted to
    avoid a storm of warnings in the log from all applications whenever
    this happens.
    
    This is also what the X11 backend does (see gdk_x_io_error).
