Fix section_occupancy: Return empty table
Fixes the functioning of the LuaATC function section_occupancy in
the presence of no trains.
Currently, if there is no train in the section,
advtrains.interlocking.db.get_ts will return a table with a nil entry.
When that nil value is passed to table.copy, Minetest throws out an error.
Instead of passing nil to table.copy, just make a new empty table.
