manifestcache: protect write with `wlock` instead of `lock`

The `wlock` is taken by both `update` and `commit` type operation. This would
help persisting the cache more aggressively.

An explicit test is introduced. However, we can already see the effect of this
change on earlier test output.

  $ hg init repo
  $ cd repo

  $ touch foo
  $ hg ci -Am 'add foo'
  adding foo

  $ hg up -C null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

this should be stored as a delta against rev 0

  $ echo foo bar baz > foo
  $ hg ci -Am 'add foo again'
  adding foo
  created new head

  $ hg debugindex foo
