stack: replace 'getstack' with direct call to 'stack'

The dedicated function do not add any value. We can update all the callers.

Check that topic without any parent does not crash --list
---------------------------------------------------------

  $ hg up other
  switching to topic other
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg topic --list
  ### topic: other
  ### branch: default
  t2@ c_b (current)
  t1: c_a
  $ hg phase --public 'topic("other")'

After changing the phase of all the changesets in "other" to public, the topic should still be active, but is empty. We should be better at informating the user about it and displaying good data in this case.

  $ hg topic
     foo
   * other
  $ hg stack
  ### topic: other
  ### branch: 

  $ hg up foo
  switching to topic foo
  4 files updated, 0 files merged, 0 files removed, 0 files unresolved

Simple test
-----------

'hg stack' list all changeset in the topic
