merge: respect parents order when using `graft` on a merge
The previous code did not record the index of the replaced parent. It was always
using the "graft" destination as `p1`. This could switch parents order in some
situation (eg: some of the evolve evolving merge case). Recording and using the
information fixes the issue in evolve.
We are not aware of core commands calling graft in that fashion, so we could not
build a simple test case for it using core commands.
