Blender Version
Broken: 45ae33a952, master, 2019-08-06
Worked: (optional)

Short description of error
the measuer tool leaks memory

Exact steps for others to reproduce the error
from the startup scene:

select default cube
enter editmode
select the Measure tool
create a measure
hold CTRL to enable snapping
move over the mesh (measure will snap to verts/edges)
release LMB so the tool finishes
exit blender
see memory leak

Error: Not freed memory blocks: 259, total unfreed memory 0.083527 MB

Measure tool will actually call ED_transform_snap_object_context_destroy on exit/finish, but for some reason the sod->bvh_trees are all NULL (even though bvhtree_from_editmesh_edges allocated them for these?)

Not quite sure whats wrong, @mano-wii: could you check?
