Reviewers by email don't have an account ID but formatting reviewers as
JSON tried to get account IDs of all reviewers and trying to get an
account ID from a reviewer by email fails with an
IllegalArgumentException.
Reviewers by email only have an email and optionally a name. Since they
don't have an account we must not invoke the account loader for them. In
addition reviewers by email cannot have approvals so we can skip the
approval format step.
Listing reviewers of a change is not available through the extension API.
This is why the test needs to make a REST call to test this
functionality.
