Subject: [PATCH] [receiver/hostmetrics] Fix failing tests (#32583)

Fixing failing tests - recover `scraperFactories` var
value after `TestGatherMetrics_ScraperKeyConfigError` and
`TestGatherMetrics_CreateMetricsScraperError` tests

Fixes https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/32536
