getAttachmentsWhenReprorcessing.js

// Courtesy of Nick Rupley from Mirth Slack - gets attachments when re-processing messages.
/* From Tony Germano
When reprocessing, whether you need this script or not depends on if you check the override existing message box or not (similar to when you double-click to create a new message)
if it's a new message id, then you need the script because the attachment is still on the old message id

// Workaround until this is done better in Mirth Connect
