Value of creator is not matching public key value used when create product

[ralupopa]

1. Create product using https://api-external.oftrust.net/polku/translator/v1/public.key
2. Try fetch the product and check the response, specifically signature block

Result
Signature block has property creator with value: https://api-external.oftrust.net/translator/v1/public.key

Wanted
Value for creator to be the one used when create product: https://api-external.oftrust.net/polku/translator/v1/public.key

Attempt to fix this was made to commit aac9614

• req.baseUrl was included in the connectorUrl.

Requires testing by PoT.

At least on test env, still visible; I left comment on internal task as well.
