Updated to add test-coverage of orphaned nodes.

We've updated how we add our fake data, such that we now add a single
orphaned node.  We do this by inserting as usual, then faking the
created_at date as being 300 seconds past the epoch.

This increases the test-coverage of db.go from 83.1% to 87.3%.
