    RTP: Fix rtpdump export
    
    Broke by 87973bf516432756f6948e969dbe9d6aa8a27017.
    
    RtpStreamDialog allocates its own rtpstream_info_t, and copies the original stream's info.
    
    Then RtpStreamDialog::on_actionExportAsRtpDump_triggered calls
    rtpstream_save with this copy.
    
    On save, reset_tap_listeners is called, and it clears all the tree items,
    destroying the allocated copy *before* it is used for the actual export.
