Missing "iss" field from /oauth2/introspect response

[vorce]

When making introspect calls I am not getting an "iss" field, despite having set the ISSUER env var.

Steps to reproduce:

docker run -d -e ISSUER=myawesomeissuer -e FORCE_ROOT_CLIENT_CREDENTIALS="admin:admin" -p 4445:4444 oryd/hydra:v0.7.7
TOKEN1=$(curl -s -kv -XPOST \
                --user 'admin:admin' \
                --url https://localhost:4445/oauth2/token \
                --header 'content-type: application/x-www-form-urlencoded' \
                --data 'grant_type=client_credentials&scope=hydra' | jq -r .access_token)
TOKEN2=$(curl -s -kv -XPOST \
                --user 'admin:admin' \
                --url https://localhost:4445/oauth2/token \
                --header 'content-type: application/x-www-form-urlencoded' \
                --data 'grant_type=client_credentials&scope=hydra' | jq -r .access_token)
curl -XPOST https://localhost:4445/oauth2/introspect -H "Authorization: bearer $TOKEN1" -d "token=$TOKEN2" -k
{"active":true,"scope":"hydra","client_id":"admin","sub":"admin","exp":1490274665,"iat":1490271065,"aud":"admin"}

Expected result: The introspect calls contains an "iss" field set to $ISSUER.

I just tried the same thing with oryd/hydra:latest with the same result.
