Unit test fix: test_cluster_remap_error (didn't fix it properly in #4030) (#4032)

## Changes

One of the unit tests (`test_cluster_remap_error`) updated in #4030
wasn't done properly, and still wasn't capturing the logs in the right
way. This PR fixes that.

### Linked issues

Follows #4030.

### Tests

- [x] manually tested (against `blueprint@cli-missing-debug-logging`)
- [x] updated unit test
