14761	Deleted featured are not removed from geojson	Alexander Kachkaev <alexander@…>	team	"I noticed that when the layer saved as a geojson contains just-deleted map features, these objects remain in the file output.

==== What steps will reproduce the problem?
1. Create a new layer and draw something like this:

2. Save the file as geojson

3. 

Delete some geometries from the layer and save it again

==== What is the expected result?

The second file is not expected to contain 'ghost' geometries, i.e. those that were just delete.

==== What happens instead?

The second file does contain 'ghost' geometries, i.e. the point with the coordinates plus two linestrings with the empty arrays of points.
