patch 9.0.1686: undotree() only works for the current buffer

Browse Source 
Problem:    undotree() only works for the current buffer
Solution:   Add an optional "buffer number" parameter to undotree().  If
            omitted, use the current buffer for backwards compatibility.

Return the current state of the undo tree for the current
