The reprint dialog shows a random file, definitely not the latest selected file

[davidzwa]

When selecting multiple printers for executing a batch reprint, a user is receiving a file which seems random.
I believe there is method to this madness, but it does not matter: the latest file to reprint is the one file which is already selected in OctoPrint.

Task description

• Fetch the job from OctoPrint, if no job exists then do not return that file
• Refer to https://docs.octoprint.org/en/master/api/job.html
• Present this in the same dialog
