merge-recursive: fix leaks of allocated renames and diff_filepairs
get_renames() has always zero'ed out diff_queued_diff.nr while only
manually free'ing diff_filepairs that did not correspond to renames.
Further, it allocated struct renames that were tucked away in the
return string_list. Make sure all of these are deallocated when we
are done with them.
