> According to OData specifications:
> [11.2.9 Requesting the Number of Items in a Collection|http://docs.oasis-open.org/odata/odata/v4.0/errata02/os/complete/part1-protocol/odata-v4.0-errata02-os-part1-protocol-complete.html#_Toc406398314]
> …
> Example 64: return the number of all products whose Price is less than $10.00
> http://host/service/Products/$count?$filter=Price lt 10.00
> The /$count segment can be used in combination with the $filter system query option.
> Using provider based on the ServiceHandler class, the following URL:
> {code}
> http://localhost/myservice/Stores/$count?$filter=ID eq '123465'
> {code}
> produces that error:
> {code}
> {
>   "error": {
>     "code": null,
>     "message": "The key value 'ID' is invalid."
>   }
> }
> {code}
> Initial analysis:
> The $count option (UriResourceCountImpl) pushes a context without any type (context.contextTypes = []).
> The $filter option then raises an exception when trying to introspect the type provided by the last URI segment.
