Add error handling to the API request

[krisgesling]

Currently no error handling. Unlikely but does happen. Could be DDG service down, or a local network error, etc.

I'm presuming that "API request" means the disambiguation request that doesn't use the ddg package here https://github.com/MycroftAI/fallback-duckduckgo/blob/21.02/__init__.py#L128 ? Or maybe Ken changed stuff enough since this issue was created that it's less relevant?

Yeah that's the one.

What happens if we pass a failed request response to ddg.Results()?

If we get None and that is handled properly then we're all good. If not we just want to handle it appropriately.
