Calling metabase.test.data/id with no args ensured the db was created,
I added that same check to the other arities of the id method.

Fixes #5424

Previously we were using the PostgreSQL driver for connecting to
Redshift. Newer versions of PostgreSQL require newer drivers that are
no longer compatible with Redshift which has prevented us from
upgrading. By switching to the AWS Redshift driver, we can upgrade the
PostgreSQL driver independently.

Fix a top level data/id call

There's a def of a data structure that contains a data/id call. This
can be a problem if the database hasn't been initialized yet. This
commit wraps it in a thunk to ensure it happens when the test run, not
when the code is compiled.
