scope.AnalyticsQueryAsync may construct Dataset query_context incorrectly?

See updated pull request https://github.com/couchbase/docs-sdk-dotnet/pull/168 for a (currently commented out) section of code which fails.

This ran previously, as I'd created (manually) a dataset with the name "bucket.scope".

However, the escaping of the name containing dash is important. I think the dotNet version generates as (in this case)

`travel.sample.inventory` 

whereas the Analytics dataset should be created (as per https://blog.couchbase.com/collections-simplify-your-analysis-with-couchbase-analytics/ ) like

`traval-sample`.inventory 

This means that now that I've corrected the Analytics setup, the dotNet sample fails with

 Unhandled exception. Couchbase.CouchbaseException: Analytics query failed: 24045

This isn't a very detailed error message (can I introspect it to get more info?) but I suspect it's constructing the Dataset name wrongly and not finding it, (as some other SDKs do exactly that)

Could you have a look and let me know if I've misunderstood usage?

NB: for the time being I've commented out the documentation of this feature.
