// This ugly query exists because when we want to mirror networks to/from
// another data store (e.g. FileDB or LFDB) it is possible to get a network
// that doesn't exist in Central's database. This does an upsert and sets
// the owner_id to the "first" global admin in the user DB if the record
// did not previously exist. If the record already exists owner_id is left
// unchanged, so owner_id should be left out of the update clause.
