Metadata not always saving

[jmgasper]

We're seeing this in dev, where metadata isn't fully saved from Work Manager:

Sample metadata in the PUT:

"metadata": [
        {
            "name": "fileTypes",
            "value": "[\"PSD\"]"
        },
        {
            "name": "allowStockArt",
            "value": "true"
        },
        {
            "name": "submissionsViewable",
            "value": "true"
        },
        {
            "name": "submissionLimit",
            "value": "{\"limit\":\"true\",\"count\":\"5\",\"unlimited\":\"false\"}"
        },
        {
            "name": "postMortemRequired",
            "value": "false"
        }
    ]

Sample response in the GET a second later:

"metadata": [
        {
            "name": "postMortemRequired",
            "value": "false"
        }
    ]
