Upserted document construction includes certain non-`$eq` filters

[toptobes]

Example is pretty self explanatory:

> await c.updateOne({ 
  arr: { $ne: [1, 2] },
  map: { $ne: { a: 1, b: 2} },
  $lexical: { $match: "match me!" }, 
  null: { $ne: null } 
}, {}, { upsert: true })
{
  modifiedCount: 0,
  matchedCount: 0,
  upsertedId: '0cad3781-4434-4120-ad37-814434c120cd',
  upsertedCount: 1
}

> await c.find().project({ '*': 1 }).toArray()
[
  {
    _id: '0cad3781-4434-4120-ad37-814434c120cd',
    null: null,
    arr: [ 1, 2 ],
    map: { a: 1, b: 2 },
    '$lexical': 'match me!'
  }
]
