Ugh, real-time timers. Can't we inject a timer for testing into the
HostContentSettingsMap instead?

[dullweber, 2017/05/03 15:59:13]

I changed the PrefProvider to use a base::Clock. It is injected from
HostContentSettingsMap. I also updated other tests that were using timeouts to
guarantee a clock difference.
