Better logging on Default Insertions

[domenukk]

When inserting a default value:

enochecker/src/enochecker/checkerservice.py

Line 191 in 8a1c823

print("Inserted default")

we should also log they key, and which value was inserted.

This makes debugging easier in case a defaultable key is missing.

• Also it shouldn't use a print, but a log.
