Log name components for UUIDv5 generation

For some reason we are unable to reproduce UUIDs for
Vulnerability::Finding objects when calculating them from the persisted
data. See https://gitlab.com/gitlab-org/gitlab/-/issues/212322#note_434346683
for a sample.

Now we will log the name we use when generating the UUID right before
we persist the object.
