`where`+`delete`+`insert` Throws Reference Object Error

[aaj3f]

Description

This is observed when running server on feature/where-syntax-update (commit SHA 7f125ccae182d4df5b1850ee64301291cf414954)

Certain where+delete+insert syntax throws an error, like in the following scenario where I want to delete any existing values on the schema:description property on ex:mosquitos and then replace them with a new insertion:

{
    "@context": "https://ns.flur.ee/",
    "ledger": "cookbook/base",
    "where": {
        "@id": "ex:mosquitos", 
        "schema:description": "?o"
    },
    "delete": {
        "@id": "ex:mosquitos", 
        "schema:description": "?o"
    },
    "insert": {
        "@id": "ex:mosquitos", 
        "schema:description": "We ❤️ All Blood"
    }
}

// =>

{
    "error": "db/invalid-query",
    "message": "Illegal reference object value"
}

Steps to Reproduce

Create Ledger

{
    "@context": "https://ns.flur.ee",
    "ledger": "cookbook/base",
    "insert": [
        {
            "@id": "ex:fluree",
            "@type": "schema:Organization",
            "schema:description": "We ❤️ Data"
        },
        {
            "@id": "ex:w3c",
            "@type": "schema:Organization",
            "schema:description": "We ❤️ Internet"
        },
        {
            "@id": "ex:mosquitos",
            "@type": "ex:Monster",
            "schema:description": "We ❤️ Human Blood"
        }
    ],
    "opts": {
        "defaultContext": {
            "ex": "http://example.org/",
            "f": "https://ns.flur.ee/ledger#",
            "rdf": "http://www.w3.org/1999/02/22-rdf-syntax-ns#",
            "rdfs": "http://www.w3.org/2000/01/rdf-schema#",
            "schema": "http://schema.org/",
            "xsd": "http://www.w3.org/2001/XMLSchema#"
        }
    }
}

Update Data (this fails)

{
    "@context": "https://ns.flur.ee",
    "ledger": "cookbook/base",
    "where": {
        "@id": "ex:mosquitos", 
        "schema:description": "?o"
    },
    "delete": {
        "@id": "ex:mosquitos", 
        "schema:description": "?o"
    },
    "insert": {
        "@id": "ex:mosquitos", 
        "schema:description": "We ❤️ All Blood"
    }
}

I was able to reproduce this in db alone, so I'll proceed with investigating it there (and fixing it there will very likely fix it in server too).

This was fixed by other fixes that just landed on main.
