Description
When the edit state of a layer is toggled off while you're tracing a new feature, the aborted trace doesn't clear up, and upon toggling edit on again resumes. It's confusing as if you move your canvas away, a/ you don't see that there's an active trace, b/ the error message is confusing when you don't know a discarded trace is still active.
Steps to reproduce- Open a project in which you can trace features against basic shapes
- Make sure you have snapping options to allow for tracing to work
- Add a new polygon scratch layer, toggle edit state to on
- Begin tracing a polygon feature while tracing is active, but don't complete the polygon
- Abort editing by toggling it off
- Toggle editing on again, notice the tracing resumes
Martin, very, very cool feature :)

Hmm just tested and obviously this behavior is the same also when tracing is not enabled - aborting editing and later turning it on again will continue with the semi-digitized feature (not just with add feature, but also other editing tools). This happens also in earlier versions of QGIS (e.g. 2.8) so I am wondering if that is a long-term bug or a feature - allowing to switch tools and come back to the digitizing.
The main point is whether this should be fixed just for tracing or also when tracing is disabled... Opinions welcome :)

With the recent commit that introduces fallback to straight line digitizing in tracing mode (06932d98de114c3ad30be5cc4442d4a8541f878b), I think this is a non-issue now... could you please test again?

Tested and works as expected.
