[sound-juicer] Remove unused helper

[Christophe Fergeau <teuf src gnome org>]

commit 7d725ce60da9e66e578d47c7dedbe1b099b836e3

    Remove unused helper
    
    With the switch to GstDateTime, we use
    gst_date_time_new_from_iso8601_string() and the
    sj_metadata_helper_scan_date() helper is no longer needed.
