Index groups that are created during init

During the initialization of a new site some default groups are
automatically created ('Administrators' and 'Non-Interactive Users').
These new groups must be added to the index so that they become
queryable. For this init must have the group index available so that
it can write the new groups to it. Reading from the index during init
is not needed and not supported.

Alternatively we could require users to run the Reindex program after
the initial site initialization, but likely many people would forget
about it and then wonder why the default groups are not available from
the group index.
