Short description of error
When adding an armature on a pruned tree created with the add-on, Blender reports a "bone not found" error, e.g.:

Exact steps for others to reproduce the error
From an empty project

Enable the Add Curve: Sapling Tree Gen add-on
Add a new Curve > Sapling Tree Gen
In the Sapling: Add Tree dialog:
- in the Geometry settings, load the weeping_willow preset.
- in the Branch Splitting settings, increase the branch splitting levels to 3. This will create long drooping branches, some of which drop below the ground
- in the Pruning settings, check the Prune option. Now all the branches will be above ground again.
- in the Armature settings, check the Use Armature option. Blender will then report the "Bone not found" error.
