Bugfix: test_delete_ws_groups_should_delete_renamed_and_reflected_groups_only (#2541)

## Changes

This PR updates an integration test that started failing after the
Databricks 0.32.0 release. In this test we check the error message
associated with an expected failure, but the message changed with the
new version of the SDK so the test now fails.

_Note: This is probably a bug introduced in the upstream SDK release._
For a call to `ws.groups.get(id)` where the ID doesn't exist:

 - Previously we would get the message: `Group with id $ID not found.`
 - As of the new release we get: `None request failed`

### Linked issues

Resolves #2539.
