Describe the bug

On a new Docker container running FreshRSS v1.26.2, the wrong iconURL is returned from the GReader API. It appears that an iconUrl is generated, but it only returns the default favicon (globe). I've verified this by running FreshRSS v1.26.1 in a Docker container and the issue doesn't occur there.

To Reproduce

1. Start a new Docker container (or any fresh install, I'm guessing)
2. Setup accounts and API access
3. Run curl -X POST -d "Email=apiuser&Passwd=apipasswd" 'HOST/api/greader.php/accounts/ClientLogin' to get API auth
4. Run curl -s -H "Authorization:GoogleLogin auth=apiuser/AUTHKEY" 'HOST/api/greader.php/reader/api/0/subscription/list?output=json' and find any RSS entry.
5. Go to the iconURL item that is returned and it should return the default favicon

Expected behavior

The correct iconUrl should be returned from the GReader API.
