source-twilio: fixes to make acceptance tests pass

[alafanechere]

What

Acceptance tests run on source-twilio were failing. I try to make the required fix in this PR.
Closes #9225

How

• Fix schemas: Add a new streams property in the calls stream's subresource_uris (probably a new subresource that is now returned by the Twilio API.
• Declare a valid primary key for the conference_participants stream
• Define message_medias and conferences as empty stream in the acceptance test config as our sandbox account does not have data for these streams
