add method insertTask(...) - inserts existing task into database, does not create new task id
populate test database with destinations to ensure integrity during tests
use autowired test task instead of ad-hoc one (to maintain database integrity)
insert existing task into database, preserve the current task id (use different method of TaskManager)
add test task to the pool (and database) to maintain db integrity when inserting task results
use 0 as engineID when inserting tasks into database (database is local for engine now)
