Previously, this test was repeatedly testing the first process in the resource. This tended to just work, but is not testing what it is supposed to. When changing it to test every resource in the scrape, it came up with issues due to the fact that not all resource attributes can always be found. This PR changes the test to look at all process resources in the scrape, and instead of asserting the presence of every resource attribute, it checks for one mandatory attribute (the process ID) and ensures that no unexpected resource attributes are added. This should reduce the flakiness of this test on other environments, while still asserting this on every process resource in the list.
