ldp:constrainedBy Links point to incorrect locations

When an ldp:constrainedBy link is included in an error response, the web app seems to expect that fedora is running in the root context of a servlet container:

For instance:

HTTP/1.1 400 Bad Request
Server: nginx/1.10.1
Date: Thu, 05 Jan 2017 20:32:57 GMT
Content-Type: text/turtle
Content-Length: 97
Connection: keep-alive
Link: <http://example.com/static/constraints/OutOfDomainSubjectException.rdf>; rel="http://www.w3.org/ns/ldp#constrainedBy"

RDF Stream contains subject(s) (http://example.com/profile) not in the domain of this repository.

When in fact, Fedora is running in the /fcrepo context
