Update services info before returning authenticators

Added RegisteredServicesCache.updateServices method which allows callers
to request an update to services for which package has been updated.

Added a call to updateServices in getAuthenticatorTypesInternal

Test: Manually tested update flow on test authenticator with an artificial
      delay in broadcast handling
