    Check if streams array exists in handle_draw_jpeg_onload
    - It seems `SpiceDisplayConn` does not always have the array `this.o.sc.streams` set.
    - It also seems (stream?) images can be loaded before `streams` is set.
    - Without `streams`, or the specific stream matching `this.o.id`, `this.o.sc.streams[this.o.id].frames_loading` cannot be accessed.
    - The check for the specific stream woth `this.o.id` is already in place, this patch adds a check for `this.o.sc.streams` in `handle_draw_jpeg_onload`.
    - There might be a better place to ensure that `this.o.sc.streams` is initialized; this quick fix saved my bacon today though.
    Might be related to, and perhaps fix:
