REVISION SUMMARY
  This is a similar to https://phab.mercurial-scm.org/rHGdd1ab72be9832584993955dfeb98d46c79602935 (test: demonstrate crash with
  in-memory rebase and copies, 2019-03-14). The new failure started with
  https://phab.mercurial-scm.org/rHG57203e0210f832b34438534770a583de35d0d6c6 (copies: calculate mergecopies() based on pathcopies(),
  2019-04-11). It happens in the call to mergemod.update() on
  rebase.py:1268 where we call mergemod.update() to graft a node. Since
  the mergecopies() rewrite, that calls _related() with the filectx from
  the overlaywctx instead of a filectx from the changectx where the file
  was last modified. Either should be fine, so I don't think that's
  a bug.
