rebase: preserve the 'intermediate-source' attribute of grafts

Preserving the 'source' attribute of grafts started with a69a77a80900, which
predates the introduction of 'intermediate-source' in 51930a7180bd by a year and
a half.  It looks like not preserving this was an oversight.

On a related note, notice how the source value of 32af76 is no longer visible in
the graph above this test.  Is it reasonable to import the sha1 translation from
evolve.py:relocate() into scmutil or similar, and use that to fixup these
attributes as well as the commit message?  (I realize that evolve is still
experimental, but I don't see a way to do this from the evolve extension.)
