Bug 1873490, part 1 - Refactor the only external call to StorageDisabledByAntiTracking - r=anti-tracking-reviewers,timhuang

Browse source 
I'm considering dropping this if statement entirely because this is only hit when we disable network state partitioning.
According to code coverage, we only see the ""_ns as the result of this ternary in our testing too.

But, if you disable network state partitioning and then block cookies from a given domain, then we would still want to partition network state I suppose, so I'll leave it like this..
