The API demo pages don't work

The API demo pages don't work.

Related to #162.

Looks like the swagger blueprint doesn't get correct URLs. Running an example when URL_ROUTE = '/trendlines' results in this URL being generated:

http://localhost:5000/api/v1/metric

Expected:

http://localhost:5000/trendlines/api/v1/metric

Preliminary investigation shows that setting url_prefix on the route definitions results in those URLs including /trendlines, but then the DispatcherMiddleware steps in and adds another:

http://localhost:5000/trendlines/trendlines/api/v1/metric

So perhaps I should nix the DispatcherMiddleware... it does seem to simply cause problems...

Note: All the above was run using tests/docker-compose.yml
