NTP SI on iOS does not respect wallpaper specific logo overrides

[kylehickinson]

Description:

When there's a specific logo passed in with a NTP SI logo it is not shown and instead the main campaign logo is always shown

Steps to Reproduce:

On Brave Dev (staging campaigns) open tabs until you begin to see NTP SI's. They will rotate through 3 different Brave Search campaigns.

Expected:

SI #1 - Woman walking away from camera, logo text is “Logo “Private, independent, & open. Search without a trace.” it should link to https://search.brave.com/?source=Private-Independent-Open-Search-Without-A-Trace
SI #2 - Woman walking with dog away from the camera, logo text is “Private, independent, & open. The search engine that doesn’t track you.” It should link to https://search.brave.com/?source=Private-Independent-Open-The-Search-Engine-That-Doesn't-Track-You
SI #3 - Logo text is “Explore freely with our unbiased, private search engine.” It should link to https://search.brave.com/?source=Explore-Freely (Same background as SI #1 but different logo and URL.)

Actual:

You only see the main campaign logo regardless of wallpaper which has the logo "Private, independent, & open. Search without a trace"
