Currently, the change stream does not log 2 objects that are being compared if there is an assertion failure. Consider the snippet:

assert.eq(bsonWoCompare(getMorePBRT, txnEvent3._id), 0);

Where if getMorePBRT != txnEvent3._id and the test case fails, we have no way to figure out what value these two objects contain.

Logging such objects' values might help in making a correlation with the C++ logs.

The proposal here is to do something like this:

Just before such assertion checks, create a dictionary containing objects been compared.
Like this for the above example:

let objectValues = {
  getMorPBRT: getMortPBRT,
  txnEvent3_id: txnEvent3._id
}

And then checking fo the condition like this:

assert.eq(bsonWoCompare(getMorePBRT, txnEvent3._id), 0, objectValues);

In case of assertion failure, the object_values will be dumped.
