SCUMM: Fix bug #3526089 - "SCUMM: ZAK Can't get objects in the bus on Mars"

Browse Source 
This fixes a regression in V1/V2 games when no actor direction
is set (like the Shuttle Bus scene in Zak V2). The regression
was caused by commit de0b5f76749add219a6b667d5d2d69fb8a86d959.
Thanks to digitall for his bisecting work, which aided a lot in
finding the actual issue for this bug
