Now when initializing the test database for sql tests,
it will load the colors persona data into the database. This will
provide a data set that tests can use without needing to call
`wtt_load`.
The main motivation is to allow for a separation of setup and test
execution that requires crossing a transaction boundary. The pgTap tests
are required to exectue as a single transaction, so that the rollback
can reset the state, and each test can be isolated. However, can cause
issues with some test senarios, particuarly with the use of some times
releated functions like `current_timestamp` and `now` which return the
time that the current transaction started. This creates an issue if a
test relies on some setup that sets a time via `now`, then an update
that expects a new time via `now`.
