field (eg, to refresh access tokens) but does *not* update anything else (which
is effectively a no-op change because in practice the only thing that it
attempted to update was "profile" but because existing fields were not
overridden, this never did anything).
Remove the "extra" argument from createUser and related functions. Add a new
"profile" option to the main options dictionary, interpreted by
defaultCreateUserHook.
This is an internal function only used by OAuth implementations and the
equivalent, so rename to a more specific name:
Accounts.updateOrCreateUserFromExternalService.
Change the signature to directly take serviceName and serviceData instead of a
nested data structure with a very specific structure. Similarly, change
Accounts.oauth.registerService's handleOauthRequest callback to un-nest the
service data.
Throw errors on misuse (if you try to use it with the "password" or
soon-to-be-introduced "resume" services, or if you don't provide an id).
Avoid doing no-op user updates if there is nothing new in "extra".
