TST: Multiple network tests fail to check that network result was successful.
Under test_google, the test_multi\* methods are not checking to see result is successful. 

Test get quote for yahoo also needs to check that result is None. 

We should also consider mocking the network object to raise URLErrors to make sure that network methods all handle them appropriately (ie they should raise the URLError unless they explicitly specify otherwise.

I can do fixes to test cases, just want to remember because you don't see it unless no wifi 

@cpcloud I'm guessing the really long request issue is because some of the test_google tests are overly ambitious and want to grab more data when probably smaller amount would work.
