Improve directory filtering to exclude archived providers

[fershad]

This tiny PR improves the filtering of providers when the Directory list is rendered.

The previous logic would only exclude providers who were marked as showOnWebsite=false. This exposed an edge case where providers might be archived (archived=true) however might still have the showOnWebsite variable set to true (showOnWebsite=true). In this case the provider would incorrectly be shown on the Directory even though they are archived.

This PR fixes that.
