fix(tests): only enforce normalization guard in record mode

The normalization guard was firing during cassette playback in CI,
breaking gooddata-fdw tests which don't call configure_normalization().
The guard only matters when recording (OVERWRITE env var set), since
playback doesn't need normalization — cassettes are already normalized.

risk: low
