    ephy-snapshot-service-test: Do not succeed when there is an error
    
    Seems it's impossible for this test to ever fail? It's printing tons of
    errors, yet still passing. Fix this to ensure the test fails properly.
    
    I haven't investigated why it's failing; we might need to disable it.
