function ManyToOne::summary_query

Build the info for the summary query.

This must:

• add_groupby: group on this field in order to create summaries.
• add_field: add a 'num_nodes' field for the count. Usually it will be a count on $view->base_field
• set_count_field: Reset the count field so we get the right paging.

Return value

The alias used to get the number of records (count) for this entry.
