Unexpected error when trying to initialize a DefaultSqlDbxIOClient

[nbondtoloka]

Describe the bug
DefaultSqlDbxIOClient throws an unexpected error if there are no DATABRICKS_HTTP_PATH or DATABRICKS_SERVER_HOSTNAME environmental variables set up.

To Reproduce
Steps to reproduce the behavior:

1. Have no DATABRICKS_HTTP_PATH or DATABRICKS_SERVER_HOSTNAME environmental variable set up
2. Try to initialize a DefaultSqlDbxIOClient
3. See the UnavailableAuthError('No available provider found')

Expected behavior
The error should say that the needed environmental variables are not set up and not that no auth provider is not found.
