[update-collection-v3] Misleading warning "Tracing config migrated"

[andrzej-stencel]

Version: v2.17.0

The warning "Tracing config migrated" is output even when there's no tracing config.

Steps to reproduce

1. Prepare basic user-values.yaml file:

sumologic:
  accessId: xxx
  accessKey: yyy
  clusterName: zzz

2. Run the migration tool ./update-collection-v3 -in user-values.yaml -out v3.yaml

Expected output

There should be no warning in the console output from the migration tool

Actual output

$ ./update-collection-v3 -in user-values.yaml -out v3.yaml
