The deprecation message is unclear and unnecessary

[PikachuEXE]

I get this all the time I start my app:
This method has been deprecated. See readme for information
which is from
https://github.com/mhenrixon/sidekiq-unique-jobs/blob/master/lib/sidekiq_unique_jobs/config.rb

unclear: If I don't search through the source of all the gems I am using, I won't understand what it means
unnecessary: I use .config already, why am I still getting it?

If I'm reading this right it will always warn when the gem is required due to this line:

https://github.com/mhenrixon/sidekiq-unique-jobs/blob/master/lib/sidekiq_unique_jobs/config.rb#L11
