Initialize in initializer lists rather than in the body (here and in other
constructors).

[Cait (Slow), 2014/04/23 23:26:55]

DefaultSearchManager takes a PrefService as input, so doing this would require a
check if profile is NULL in the initializer list -- seemed cleaner to do it here
(since GetPrefs() already handles this check).

   Init(initializers, count);
