Fix `databricks configure` if new profile is specified (#1030)

## Changes

The code included the to-be-created profile in the configuration and
that triggered the SDK to try and load it. Instead, we must use the
specified host and token directly.

## Tests

Manually. More integration test coverage tbd.
