test-context: add a case demonstrating manifest caching problem

This issue was discovered when testing absorb on Windows. What happens are:

  1. ctx.p1().manifestctx gets cached.
     let's call ctx.p1().manifestctx._revlog() "mrevlog1"
  2. repo.manifestlog gets invalidated.
     let's call repo.manifestlog._revlog "mrevlog2"
  3. repo.commitctx(ctx)
     commitctx uses ctx.p1().manifestctx and writes to "mrevlog1"
  4. repo[n].manifest()
     cannot find the manifest node in "mrevlog2"

This patch adds a test case to reproduce the issue.
