checkheads: add a small debug message in case were we give up fast
When node is unknown we assume it will stay. Yet, we might have markers to it
that are going to be pushed. However, we do not have branch (ancestors)
information unless we are very lucky an all of them are pruned. So for now we do
not do anything assuming this will be rare.
We still add a small debug message to help detecting such situation in the
future.
