In a couple of UpdateCheckerTests, multiple update checks are triggered in the same test and a url post interceptor is used to inspect the requests.
Once an expectation for the url post interceptor is matched, it is removed from the interceptor queue. However, the tests don't create new expectations as the tests are making progress. Therefore, subsequent requests don't have expectations to match. As a side effect, for an unknown reason, the calls where no expection is set take about 1000 ms each to complete, and thus, the test execution takes ~10 seconds to run
