Ensure that subdividing "Bone" results in a chain "Bone", "Bone.001",
"Bone.002", etc.
Before this commit the order would be "Bone", "Bone.004", "Bone.003",
etc.
This might break add-ons that assume to know the bone names before the
actual subdivision happens. This would always have been fragile, as
there may, for example, already have been a "Bone.001"; in that case
subdividing "Bone" would result in "Bone", "Bone.002", etc. Instead, the
parent-child chain should be followed.
