histedit: use base for computing renames when folding (issue3729)

When a file was renamed in the very first changeset being histedited,
the rename was not detected. Consider a history like this:

   0  base: add a.txt
   1  first: rename a.txt to b.txt
   2  last: edit b.txt

When 1 and 2 are edited, copies.pathcopies(first, last) correctly
returns that nothing was renamed. We must instead use
copies.pathcopies(first, last) to detect the initial rename.
