Scheduled backups "Taken By" user inconsistent

Bug Report

System Information

• Ubuntu 18.04.5 LTS
• 2.0.6.6
• Mainline

I confirm:

• [x] that I have searched for an existing bug report for this issue.
• [x] that I am using the latest available version of AMP.
• [x] that my operating system is up-to-date.

Symptoms

Scheduled backups do not consistently appear to be from the same user. I would expect either the original schedule creators username or SYSTEM. What I am actually seeing is one or the other, with no discernable pattern with the limited data set I have available.

Reproduction

From clean install:

• Create an Instance (Minecraft in this case)
• Set up as normal (We just need files)
• Create a Schedule trigger (In my particular case it was once every 24 hours)
• For tasks add "Take a Backup"

Needs a retest because some parts of the session tracking were changed.
