  - Allow to cancel waiting tasks for non-existing repos without scheduling them
    
    A waiting task for a non-existing repository can come into existence
    when the repository gets deleted before a waiting task gets scheduled,
    and thus becomes a running task.
    
    A waiting task for a non-existing repository cannot be (re)scheduled
    because there is a check for repository existence in that code-path.
    However, such a task would remain in the waiting queue and rescheduling
    would be tried again and again without a chance to get finished as the
    only way for a task to get finished was to run it.
    
    This change allows to finish a waiting task when its repository doesn't
    exist. The ReplicationTasksStorage now tries to delete task file(s)
    from both running and waiting directories.
