Streamimg mode doesn't record point when starts after edit geometry

Streaming mode can be started in two cases. One for the new feature, and the second, when used hits edit geometry and then starts streaming mode.

In the first case, the streaming mode works as expected. In the second case, the streaming is running, but no new points are recorded. The expectation is, that new points are recorded into the feature. The second option how to fix this would be to allow streaming mode for geometry editing of already existing features.

Scenario

1. Have a multipoint feature project (ex tc04_recording)
2. record a multipoint feature and hit save
3. edit the geometry of the feature and on the map, canvas hit 3 dots hit Streaming mode and then hit Start streaming
   -> No new points are added to the feature

Reproduce the issue with the tc04_recording multipoint feature project: save a feature, edit its geometry, then open the three-dot menu, start Streaming mode, and observe whether points are added. Trace the existing streaming and geometry-editing entry points, then verify that the expected new points are recorded or that the unsupported editing flow is clearly prevented.
