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"
