tree: accept null ids in existing trees when updating

When we add entries to a treebuilder we validate them. But we validate even
those that we're adding because they exist in the base tree. This disables
using the normal mechanisms on these trees, even to fix them.

Keep track of whether the entry we're appending comes from an existing tree and
bypass the name and id validation if it's from existing data.
