The updated metrics responses will not be sent to p3a-json.brave.com

[GeetaSarvadnya]

Description:

On profileload, the default response values for all the metrics are sent to p3a-json.brave.com endpoint over the network in Charles. But the updated values are not sent from client to server hence the updated values are NOT shown over the network via p3a-json.brave.com

Steps to Reproduce

1. Clean profile 1.46.x
2. Wait for the p3a-json.brave.com enpoint to show up in Charles
3. Brave.NTP.SponsoredImagesEnabled response value is 1 as expected
4. Open settings and navigate to New Tab Pages->Image Type-> Sponsored was default option, select default images option
5. Waited for more than 1 hours 30 mins
6. Brave.NTP.SponsoredImagesEnabled response value is 1 instead of 0

Actual result:
The updated metrics responses will not be sent to p3a-json.brave.com

Expected result:

The updated metrics responses should be sent to p3a-json.brave.com
