Added with_connectivity_check decorator to allow explicitly checking a website as a proxy for seeing if there is network connectivity leading to a connection reset issue (GH3982, GH3985, GH4028, GH4054) • Fixed failing tests in test_yahoo, test_google where symbols were not retrieved but were being accessed (GH3982, GH3985, GH4028, GH4054)
