Details loads panel even if the details attribute value is NODATA

[MV88]

Description

the reason this issue occurs is because the action OPEN_DETAILS_PANEL is triggered here because
it finds among map attributes the showAtStartup to true but the details are empty --> NODATA

{
    "AttributeList": {
        "Attribute": [
            {
                "name": "owner",
                "type": "STRING",
                "value": "admin"
            },
            {
                "name": "detailsSettings",
                "type": "STRING",
                "value": "{\"showAsModal\":false,\"showAtStartup\":true}"
            },
            {
                "name": "details",
                "type": "STRING",
                "value": "NODATA"
            },
            {
                "name": "thumbnail",
                "type": "STRING",
                "value": "rest/geostore/data/1000024888/raw?decode=datauri&v=e1b32f50-b8ed-11ed-9b87-81c79c8f4695"
            }
        ]
    }
}

we should prevent to the action to be dispatched if NODATA else we have also to check the value from showAtStartup flag to be true, so we have to extend condition

How to reproduce

open a map that has details set with nodata and showAtStartup to true (use this map)

Expected Result

to not load the panel
Current Result

loads the panel
