Description

Previously, if

1. an instance was created from a predicted instance with no track assigned,
2. then a track was assigned to the new instance,
   the predicted instance would not be assigned the track.

This PR ensures that the linked predicted instance is assigned the same track as its linked counterpart.

Other minor fixes:

• Remove unnecessary print statement from runners.py added in Remove low-scoring predictions before merging inference results #817
• Fix TypeError print statement in instance.py

Types of changes

• Bugfix
• New feature
• Refactor / Code style update (no logical changes)
• Build / CI changes
• Documentation Update
• Other (explain)

Does this address any currently open issues?

Assigning user instances to tracks unlinks them from predicted #866
