fix #H9084 - teleported boulder left stale screen

Browse Source 
Report was for Sokoban but it applied anywhere:  if a teleported
boulder landed in a pit or trap door or hole and flooreffects() used
it up (so returned True), rloco() didn't update the location it was
teleported from and it appeared not to have moved.  (Line of sight was
updated to reflect its absence but map spot wasn't redrawn without it.)
