Duo Mobile MFA authentication gets triggered 6 times at once

Hello!

With Snowflake we are using the [Duo Mobile multi-factor authentication service](https://docs.snowflake.com/en/user-guide/security-mfa). It pings my phone with an Accept/Deny message. Acceptance is cached for 6 hours.

When I use the Wizard extension, Duo Mobile is triggered six times at once. This will happen again for me in about 4 hours, since this happened 2 hours ago (and has been happening since I started using the extension a while back). I think this would be prevented if Wizard did one connection to dbt / snowflake, and once that is successful, it does the next five.
