Fixed an HTTP 404 response during sync from registry.redhat.io.

Whenever a token expires a new token is requested.
The 404 sync problem was triggered because the accept headers that
were passed originally with the expired token were not passed to the
re-newed token. As a result the registry was redirecting to the wrong
schema version (schema1, which is unsupported since july 2022
https://access.redhat.com/articles/6138332) because of absense of the
accept headers.

closes #974
