Delete-where transaction fails to delete all matching records

[aaj3f]

Description

Encountering a bug when using http-api-gateway to specifically delete all s-p-o triples for any subject with any value on a particular property, e.g.

    "txn": {
        "delete": ["?s", "?p", "?o"],
        "where": [
            ["?s", "schema:description", "?o"],
            ["?s", "?p", "?o"]
        ]
    }

Some of the subjects will get all facts deleted, but some subjects remain in their entirety.

Steps to reproduce:

1. Create Ledger

{
    "ledger": "delete/error",
    "defaultContext": {
        "id": "@id",
        "type": "@type",
        "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#"
    },
    "txn": [
        {
            "@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"
        }
    ]
}

2. Submit transaction

{
    "ledger": "delete/error",
    "txn": {
        "delete": ["?s", "?p", "?o"],
        "where": [
            ["?s", "schema:description", "?o"],
            ["?s", "?p", "?o"]
        ]
    }
}

3. Query subjects w/ any value on schema:description

{
    "ledger": "delete/error",
    "query": {
        "selectDistinct": {"?s": ["*"]},
        "where": [["?s", "schema:description", "?o"]]
    }
}

// =>

[
    {
        "id": "ex:w3c",
        "rdf:type": [
            "schema:Organization"
        ],
        "schema:description": "We ❤️ Internet"
    }
]
