Improve resolution comment

[kmate-ct]

See #379. This changes the current resolution comment from:

# duplicates in org.threeten:threetenbp downgraded to 1.6.8
# - com.google.cloud:google-cloud-pubsub:1.123.0 wanted version 1.6.5
# - com.google.cloud:google-cloud-storage:2.14.0 wanted version 1.6.3

to:

# duplicates in org.threeten:threetenbp promoted to 1.6.8
# - com.google.cloud:google-cloud-pubsub:1.123.0 wanted version 1.6.5
# - com.google.cloud:google-cloud-storage:2.14.0 wanted version 1.6.3
# - com.google.cloud:google-cloud-storage:2.27.0 (evicted) wanted version 1.6.8

It would actually even better if the resolution comment of com.google.cloud:google-cloud-storage would not be empty, but would state that 2.27.0 was present in the graph, but not chosen because of the fixed version.
