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"

basic test for hg debugrebuildstate

  $ hg init repo
  $ cd repo

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

  $ touch baz
  $ hg add baz
  $ hg rm bar

  $ hg debugrebuildstate

state dump after

  $ hg debugstate --nodates | sort
  n 644         -1 bar
  n 644         -1 foo

status

  $ hg st -A
  ! bar
  ? baz
  C foo

  $ cd ..
