Related Asset Cache Titles aren't being used in some cases

[cmcfadden]

Sample asset: https://dcl.elevator.umn.edu/asset/viewAsset/56e0267b7d58ae2e318babc5

New UI:

Old UI:

Values are being served in the relatedAssetCache (measurement for example):

        "56e0267b7d58ae2e318babc9": {
            "primaryHandler": null,
            "readyForDisplay": true,
            "relatedAssetTitle": [
                "59 m"
            ]
        },

I believe this is because RelatedAssetWidget.vue passes the assetCache in as assetCacheItem but AccordionRelatedAssetWidgetItem.vue is expecting it to be named assetCache? Didn't push a commit cause I might be misreading.
