Remove unused actors and navmeshes on update
When there is only one actor (player) on a scene and it moving to other
cell first it will be removed from navigator then added. Remove cause
navmesh removing for its half extents. After it is added navmesh for
same half extents is created and added. While this all happens there are
still jobs for old navmesh are processing. Old navmesh still exists
because it is stored by shared pointer. So jobs take tiles from cache
and place them into old navmesh. After that other jobs take same tiles
from cache (half extents and coordinates are equal) and place them into
other navmesh. dtNavMesh changes tile data on add and remove. Adding tile
to two dtNavMesh corrupts tile in both nameshes.
