clone: make sure we warm the cache after a clone

This work around any deviciency/limitation of the clone process. In our case
this ensure the persistent nodemap exist with valid content.

Ideally, the cloning process would also do "the right thing". However since
older server will never be able to do "the right thing". The local workaround
will be necessary anyway.

I am not worried by the performance impact of this as `hg clone` is non-instant
on large repositories where is could matters. Warming the cache if they are
already correct is very fast. And if they are not already warm, this seems like
a good time to do so.

This impact various test as more cache are now warmed sooner, all the change
should be harmless.

Default queue:

Applied patches in default queue:

  $ hg qap

Try to change patch (create succeeds, switch fails):

  $ hg qqueue foo --create
  abort: new queue created, but cannot make active as patches are applied
  [255]

  $ hg qqueue

Empty default queue:

  $ hg qpop

Switch queue:

  $ hg qqueue foo
  $ hg qqueue

List queues, quiet:

  $ hg qqueue --quiet

Fail creating queue with already existing name:

  $ hg qqueue --create foo
  abort: queue "foo" already exists

  $ hg qqueue

Create new queue for rename:

  $ hg qqueue --create bar

  $ hg qqueue
  bar (active)

  patches

Rename queue, same name:

  $ hg qqueue --rename bar
  abort: can't rename "bar" to its current name
  [255]

Rename queue to existing:

  $ hg qqueue --rename foo
  abort: queue "foo" already exists
  [255]

Rename queue:

  $ hg qqueue --rename buz

  $ hg qqueue
  buz (active)
  foo
  patches

Switch back to previous queue:

  $ hg qqueue foo
  $ hg qqueue --delete buz

  $ hg qqueue
  foo (active)
  patches

Create queue for purge:

  $ hg qqueue --create purge-me

  $ hg qqueue

  patches
  purge-me (active)

Create patch for purge:

  $ hg qnew patch-purge-me

  $ ls -1d .hg/patches-purge-me 2>/dev/null || true

  $ hg qpop -a
  popping patch-purge-me

Purge queue:

  $ hg qqueue foo
  $ hg qqueue --purge purge-me

  $ hg qqueue

Unapplied patches:

  $ hg qun
  $ echo c > a
  $ hg qnew -fgDU otherstuff

Fail switching back:

  $ hg qqueue patches
  abort: new queue created, but cannot make active as patches are applied
  [255]

Fail deleting current:

  $ hg qqueue foo --delete

Switch back and delete foo:

  $ hg qqueue patches

Tricky cases:

  $ hg qqueue store --create
  $ hg qnew journal
