Description
The QgsPoint class does not properly store empty point geometries. For example, from the python console in QGIS 3.0.3:
> QgsPoint().isEmpty()
False
> print(QgsPoint().asWkt())
Point (0 0)
> print(QgsPoint().createEmptyWithSameType().asWkt())
Point (nan nan)
In comparison, for a LineString:
> QgsLineString().isEmpty()
True
> print(QgsLineString().asWkt())
LineString ()
The results observed for LineString are consistent with those for QgsPolygon and QgsGeometryCollection.
