hg: make "_outgoing()" return empty list instead of "None"

This patch makes "_outgoing()" return empty list instead of "None", if
there are no outgoing changesets, because:

  - returning "None" requires callers to examine whether returned
    value is "None" or not explicitly, if callers want to execute loop
    on returned value, but

  - there are no explicit needs to return "None"

#if unix-permissions no-root

  $ hg init a
  $ cd a
  $ echo foo > b
  $ hg add b
  $ hg ci -m "b"

  $ chmod -w .hg/store
