Download instead of subscription page is shown for dowjones referral promo

[btlechowski]

Steps to Reproduce

1. (Important) Uninstall Brave Browser with User Data to have a Clean install
   
2. (On Windows )Download stub/mini installer and rename it to BraveBrowserSetup-dowjones-barrons.exe
3. Run the stub/mini installer
4. After Brave has started wait for https://brave.com/dowjones-barrons page to be shown (can take up to 60 seconds)

Actual result:

The Download page is shown.

The Underlying issue is lack of "X-Brave-Access-Key" Header.
The header is listed in Local State file (located in [user]\AppData\Local\BraveSoftware\Brave-Browser\User Data\)

The headers in the Local State file cannot handle more than one entry.
The subscription page is shown if I modify the Local State file to:

"referral": {
    "download_id": "d63858c3-985f-4cec-b76d-88136d03bef6",
    "headers": [{
            "cookieNames": [],
            "domains": ["brave.com", "staging.brave.com"],
            "expiration": 3.1536e+10,
            "headers": {
                "X-Brave-Access-Key": "BBOfz269pb6"
            }
        }
    ],
    "promo_code": "dowjones-barrons"
}

from

"referral": {
    "download_id": "d63858c3-985f-4cec-b76d-88136d03bef6",
    "headers": [{
            "cookieNames": [],
            "domains": ["marketwatch.com", "barrons.com"],
            "expiration": 3.1536e+10,
            "headers": {
                "X-Brave-Partner": "dowjones"
            }
        }, {
            "cookieNames": [],
            "domains": ["brave.com", "staging.brave.com"],
            "expiration": 3.1536e+10,
            "headers": {
                "X-Brave-Access-Key": "BBOfz269pb6"
            }
        }
    ],
    "promo_code": "dowjones-barrons"
}

Expected result:

The Subscription page is shown

Still reproducible on Windows with the exact steps from OP.
