Do not show the same Brave Ad more than once every hour - follow up to 5281

[LaurenWags]

Description

Follow up to #5281

While testing the above issue I noticed that I got the same ad 2x in a row. Per discussion with @tmancey it is likely due to #4207.

Happy to share logs/a profile if needed (Have already shared these items with @tmancey ).

Steps to Reproduce

1. Clean profile
2. Enable Rewards
3. Set ads to 5 per hour
4. Visit a site that will be classified so an ad notification can be generated.
5. Browse so that you continue to get ads (if you need additional details here - DM me)

Actual result:

First and second Ad are from the same campaign_id which has a dailyCap of 1.

Expected result:

Shouldn't see the same ad 2x in a row - especially since the dailyCap is 1.

Reproduces how often:

easily

Same here but on Linux (OpenSuse) Version 0.69.135 Chromium: 77.0.3865.120 (Official Build) (64-bit)

Set 5 ads per hour - Auto-contribute off (I'm not stingy I just prefer to Tip and I miss the Muon version which was better, particularly the centre console part, without the few bugs of course)

I received the same ad twice; I think it was within the space of five minutes. I was using tor or private tab at the time, when I clicked on the ad I didn't immediately go over to see it open in the normal window tab. Naturally I closed the second ad because it was the same one.

@NumDeP Further improvements to show the same ads less frequently are going through testing and will be rolled out in a future general release

@LaurenWags Can you please retest this on the latest nightly build

[tmancey]

Won't fix as already fixed on latest nightly
