Revert "Reversed crowd deny preload list logic"

This reverts commit c94520a9.

Reason for revert: Found bug in CL

Original change's description:
> Reversed crowd deny preload list logic
> 
> The crowd deny preload list now contains sites with a site reputation
> of UNSOLICITED_PROMPTS. If a site is not on the preload list the normal
> UI is used, otherwise a safe browsing ping is made to ensure that the
> preload list is accurate.
> 
> Unit tests and test-fixes in a follow-up CL: For the purposes of speed
> I have removed the failing test, will be re-added in the follow-up CL
> along with new tests to account for this logic change.
> 
> Bug: 1042611
