[0.2.5] Owner may magically escape Stocks on 'Rest|Sleep'

[Zsar]

Save before step 2 uploaded here.
(I used #321 rebased onto the 0.2.5 HEAD, but it should not make a difference: Transition between 'Night Time' and 06:00 is instantaneous - and refills Stamina anyway.)

Steps to reproduce:

1. have owner stuck in Stocks with 0 Stamina at Night Time, with your next encounter 1 day in the future
2. Rest|Sleep
3. any of these effects may happen:
   1. "<owner> orders you to sleep together with him." and is physically present.
      (They will not teleport back into the Stocks afterwards.)
   2. "<owner>, your owner, wants to approach you today." (- Okay, they are allowed to want to.)
   3. owner has teleported into your cell

Expected behaviour: 3.1 and 3.3 should not happen.
(And the owner should still be stuck in Stocks. I do not think I can check that, as they might legitimately escape in the time passing while walking there?)
