Previously, if an error was returned from an Electrum server (such as "server busy") it would throw a NetworkException that would be caught outside of the server loop and cause the entire request to fail. Instead of throwing an exception, I am now logging the error and returning null, in the same way we do for IOException and NoSuchElementException further up in the same method. This allows the caller - most likely connectedRpc() - to move on to the next server in the list and try again. This should fix an issue seen where a "server busy" response from a single server was essentially breaking our implementation, as we would give up altogether instead of trying another server.
