Raw spec not provided to Specification class constructor on clone, causing internal server error

[CodeAdraas]

Hi, I don't really know the details as of why, but I notice that after any POST request the specification in the SwaggerUI middelware instance clones itself. However, in the cloning process, the Specification constructor is provided with the validated spec mapping instead of the raw spec the constructor actually expects. Then consequently after loading the spec from it's served URI, the server crashes.
By changing self._spec to self._raw_spec on line 209 in connexion/spec.py seems to fix the issue.

Is this issue possibly related to this commit: bb48fb3e

This issue may be a duplicate of issue #2028

I don't see overlap between my error and #2028 apart from someone fixing the error in the same way.
