Error message on "Run updates" when upgrading to 2.x

With installed version 7.x-1.6, upgrading to 7.x-2.0-beta1, "Run updates" gives this message:

    Notice: Undefined index: entity keys in RegistrationViewsController->views_data() (line 169 of /usr/share/nginx/html/sites/all/modules/contrib/registration/modules/registration_views/registration_views.module).

I then see two updates:
registration module

    7200 - Add registrant entity fields to the registration_type table
    7201 - Rename user id to registrant id because we are registering more than just users.

Both updates run fine, no errors, module seems to work as before after upgrade.
