Bug in stub parameter matching

[rlsf]

Describe the bug
similar to #2677 , looks like deep equal behavior has regressed in sinon 21.0.2.
comparing stub arguments succeeds for native variables, but fails for object.
in this case, mongo sequence comparison.

To Reproduce
use the following two tests, both succeeed with sinon 21.0.1, however the first one fails in sinon 21.0.2:

describe.only('test sinon object comparison', () => {
  class TestDao {
    getRawObjects ({ param1, param2, seq, limit, sort }) {
      const q = { param1, param2 }
      if (seq) {
        q.seq = { $gt: new Mongo.ObjectId(seq) }
      }
      this.getObjects(q, limit, sort)
    }

    getObjects (query, limit, sort) {
      // do something
    }
  }
  it('compares objects with sinon.assert, including mongo ObjectId conversion', () => {
    const query = { param1: 'str', param2: 'foo', seq: '5feb913181428ef0bb81524a' }
    const expectedQuery = {
      param1: 'str',
      param2: 'foo',
      seq: { $gt: new Mongo.ObjectId(query.seq) }
    }
    const instance = new TestDao()
    sinon.stub(instance, 'getObjects').resolves([])
    instance.getRawObjects({ ...query, limit: 100, sort: { sort: 'desc' } })
    sinon.assert.calledOnceWithExactly(instance.getObjects, expectedQuery, 100, { sort: 'desc' })
  })

  it('compares objects with sinon.assert', () => {
    const query = { param1: 'str', param2: 'foo' }
    const expectedQuery = {
      param1: 'str',
      param2: 'foo'
    }
    const instance = new TestDao()
    sinon.stub(instance, 'getObjects').resolves([])
    instance.getRawObjects({ ...query, limit: 100, sort: { sort: 'desc' } })
    sinon.assert.calledOnceWithExactly(instance.getObjects, expectedQuery, 100, { sort: 'desc' })
  })
})

Expected behavior
both tests should succeed.

I have seen a similar issue with several tests involving Mongo ObjectId breaking from 21.0.1 to 21.0.2.
