[kwin-mv-activity] activities might be stopped. they have to be filtered out

```
[CURRENT] 00000000-0000-0000-0000-000000000000 NAME (ICON_PATH)
[STOPPED] 00000000-0000-0000-0000-000000000000 NAME (ICON_PATH)
[RUNNING] 00000000-0000-0000-0000-000000000000 NAME (ICON_PATH)
```

currently, the script only expects CURRENT and RUNNING as status
