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.
