update debug_lua check to match passed in arg type

[JeremiahChurch]

I believe this was introduced with SidekiqUniqueJobs::Script::Caller::normalize_argv

The lua scripts check for a value of "true" for debug_lua but normalize_arg changes that to integer 1 that looks to be typed to a string when it gets to the lua script (I don't know lua in any way so this could very well be wrong)

def normalize_argv(argv)
  argv.each_with_index do |item, index|
    case item
    when FalseClass, NilClass
      argv[index] = 0
    when TrueClass
      argv[index] = 1
    end
  end
end

also remove unused toboolean in lua scripts

I have no idea how to add a test for this.

This looks sane; I don't know if testing is possible since it happens inside redis. One would have to subscribe to the log file of redis.

The change you are referring to was done because of redis-client not supporting additional data types. This was one of the hardest parts of sidekiq 7 compatibility.
