Referential#create_schema: Log benchmark time to create

We want some measurements for how long it takes to create schemas to
give us some data to decide whether to put `#create_schema` in an
`after_commit` somehow (it didn't work the simple way). This at least
gives us a better idea of what's going on and how our table lock is
performing.
