Summary

Fixed deployment agnostic integrations test

More details

• Make API call for fetching integrations before each test.
• Casted Array to Set in order to avoid duplicated values.

LGTM, but my personal nit would be to create a transformation function for the integration.name plucking.
Smth like:

const name = (integration: Integration) => integration.name

Then use is like:

        preExistingIntegrations = (
          await callApiAs({
            roleScopedSupertestWithCookieCredentials: supertestAdminWithCookieCredentials,
          })
        ).integrations.map(name);
