Delay bookmarks load while the profile is loading.

 include_rules = [
   # Bookmarks is being made into a component (it will end up at

looks like you need to sync your checkout. I have already removed this entry.

This is bad (I saw the comments above and below). However, I think this is the
right solution for now and matches the existing factories. In my opinion:
* The right place for startup_task_runner_service.h is in
chrome/browser/profiles/ (where I put it)
* All the factories should probably live in chrome/browser/profiles/ to avoid
all this include mess.

Let me know if you have a different solution here.

The decision is from Scott, so I'll let him decide if he will be fine in adding
yet another 'dependency'. But I wish you could try hard to avoid adding another
one here!
