[chore][receiver/hostmetrics, exporter/awsxray] Fix some more empty I…

…Ds (open-telemetry#30994)

**Description:** 

- Makes the test on awsxray exporter use the
`exportertest.NewNopCreateSettings().ID`. This is because this is the ID
passed to `newTracesExporter`:
https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/2f5b0bc52cd160886b4e1ee03461704d6c440a8d/exporter/awsxrayexporter/awsxray_test.go#L109
Currently, this makes no difference, but it will once the ID on
NewNopCreateSettings is fixed.
- Also fixes the hostmetrics receiver ID, just for fun :)
