Title: Do not set geometry by default

A feature can have a geometry whose value is an `ol.geom.Geometry` instance or `null`. A feature can also have no geometry property. By default, a feature has no geometry property. To set a geometry, one can be passed to the constructor (including null) or passed to `setGeometry()`.

See #2059.
