Can we lazily initialize this?

[afakhry, 2016/06/02 01:43:40]

What's the point? It will be needed in the constructor to set it for the
|main_context_|, so lazily ends up being right away. Unless you mean something
else?

[Devlin, 2016/06/03 21:26:47]

My thought was that we could move the UserPrefs::Set() call into the
initialization of the pref service as well.  In practice, though, this probably
doesn't matter much.  This should be fine.
