Broken OpenAPI doc links when deployed as serverless

[demeringo]

Bug description

There remain a problem with the links in openapi doc that do not include the default stage prefix used when deploying with the serverless framework.

The OpenAPI doc is well served and displayed but the links used to test the API do not work.

Note: this issue would disappear if using a custom domain (like dev.boa.my-domain.com and prod/boa.my-domain.com).

For example:
OpenAPI is pointing to this URL (without the dev prefix):

https://1rq5nf92sb.execute-api.eu-west-1.amazonaws.com/v1/server/all_default_models

while content is served from the same URL (but with the dev prefix):

https://1rq5nf92sb.execute-api.eu-west-1.amazonaws.com/**dev**/v1/server/all_default_models

Expected behavior

Open API spec links should work in sls deployment

The trik seems to use root_path instead of openapi_prefix

Commit 6fe3498 should fix it.
