Fixed auth login ignoring DATABRICKS_CONFIG_FILE environmental variable when saving profile (#3266)

## Changes
Fixed auth login ignoring DATABRICKS_CONFIG_FILE environmental variable
when saving profile

## Why
Fixes #1971

## Tests
Added acceptance regression test.

Removed the tests here because OAuth flow requires a browser and does
not currently work on GH runners

2f8c4a6

The test passed locally though
