This should take a Profile*, seeing as implementors simply look up a Profile*
from profile_path anyway.

I don't think ui/app_list shouldn't depend on Profile.

Good point. This method should probably not be in this interface at all. It
would go better in the implementation (ie: ChromeSigninDelegate) which deals
with Profile*s.

Done.
