[Tiles API] Inconsistent workspace separator

[allyoucanmap]

In a collection request we have styles with the following id structure {workspace}__{styleName} Example: http://localhost:8080/geoserver/ogc/tiles/collections/vtp:Daraa_DTED return

{
    "id": "vtp:Daraa_DTED",
    "title": "Daraa_DTED",
    ...
    "styles": [
        {
            "id": "vtp__hillshade",
            "title": "Daraa_DTED",
            "links": [
                ...
            ],
            "htmlTitle": ""
        },
        ...
    ],
    ...
}

if we use id described above in the tiles template we get following error

styleId = vtp__hillshade http://localhost:8080/geoserver/ogc/tiles/collections/vtp%3ADaraa_DTED/map/vtp__hillshade/tiles/EPSG:900913/EPSG:900913:14/6619/9836?f=image%2Fpng

{
  "code": "NoApplicableCode",
  "description": "Problem communicating with GeoServer\nExpected: RenderedImageMap, got null"
}

but if we change the separator to : the request returns the tile

Should have been fixed, can you verify?
