Corrected resource leak when adding in EDIT mode

Patch D10035

Addon: Bolt Factory: Corrected resource leak when adding in EDIT mode

Adding a bolt while in edit mode would *replace* the current object's mesh data block with a new one, and then fail to remove the original mesh data block.

Now the original mesh is updated in-place, preserving its name and avoiding orphan data blocks.
