Exception "Value cannot be null" when logic but no filters

**Case:** Kendo UI Combobox ads a `Logic` even though there is no filter.

**Url:** ?take=80&skip=0&page=1&pageSize=80&filter%5Blogic%5D=and

**Exception:** `Value cannot be null`

**Hack before call to `ToDataSourceResult` :**
```
public HttpResponseMessage GetMedia([FromUri] DataSourceRequest request) {
	if (request.Filter is {Filters: null}) {
		request.Filter.Logic = null;
```
