Make SQLite random IDs unique across tables
We now have an invariant that no two IDs are the same across tables. We
also assume that only one instance will ever write tensors to a given
run. This approach to IDs also allows us to be more carefree about
garbage data, so we don't need the transactions anymore. It also brings
latency down from 16ms to 8ms.
