QOL improvement: "Don't prompt for a direction for an action if there…

… is only one direction possible" (CleverRaven#33431)

* Fixed "Don't prompt for a direction for an action if there is only one direction possible CleverRaven#33402" - for lockpicking

* Added message and cancel action if there is no lock to pick
