error without queues configuration

[flavono123]

# config/delayed_job_master.rb
# Error configuration
add_worker do |worker|
  worker.queues
  # or without above code
  ...
end
...
# Working configuration
add_worker do |worker|
  worker.queues []
end
...

To set worker's queues as default, the all available queues, the configurations worker.queues (nil) or not declare anything are not working with followed error message:

NoMethodError: undefined method `any?' for nil:NilClass at /mnt/crema-bg-rails/shared/bundle/ruby/2.7.0/gems/delayed_job_master-2.0.0/lib/delayed/master/monitoring.rb: 32

Set it as an empty array, it works(worker.queues []). It seems like a bug. (If nil is respond to #any? and it returns true?)

IMO, the reason is from that configuration methods are defined both reader and writer with the same method name:

How about separate them? In #queues and #queues=?
