Fix exporting empty vector layers to OWSContext.

Browse Source 
When a vector layer is exported to an OWSContext document, we throw an
exception when the layer contains no features, and the geometries are to be
exported inside of an InlineGeometry-element.

This commit fixes this behaviour by exporting sth. like this in such cases:

<Layer name="vector" hidden="0">i
  <ows:Title xmlns:ows="http://www.opengis.net/ows"/>
  <InlineGeometry/>
</Layer>
