fix(debug): avoid printing trusted symbol in debug output

[vkarpov15]

Re: #15263

Summary

Right now trustedSymbol shows up in debug output, which can be extra confusing when debugging populate issues because populate adds trusted symbol by default:

Mongoose: groups.find({ key: { '$in': [ ObjectId("67b887650fca90b537952220"), ObjectId("67b887650fca90b537952224") ], [Symbol(mongoose#trustedSymbol)]: true }}, { skip: undefined, limit: undefined, perDocumentLimit: undefined })

This PR removes trustedSymbol from debug output.
