[BUG] First call to CREATE OR REPLACE TABLE shows confusing INFO

[randerzander]

If the first table a user creates is created with CREATE OR REPLACE syntax, they get a confusing INFO:

CREATE OR REPLACE TABLE stations WITH (
    location = '/raid/weather_meta/stations.parquet',
    gpu=True
)

# in Jupyter, red INFO line:
No tables are registered.

The table is successfully created, but the INFO message makes it seem like it might not have been.

Is there a reason to emit this message at all?

No, I'm not sure why we choose to log that message at the warning level, as there are various cases where one might perform SQL queries without actually registering any tables - I can start off a PR switching this to a debug level log, and also look through the code to see if there's any other places where it might be more fitting to switch the log level.
