Supported :image_size as Symbol in authentication options

Allowed :image_size as Symbol in authentication options

👍 Just ran into this issue where I specified the image_size as a symbol and it didn't work.

I think:

 image_size = options[:image_size].is_a?(String) ? options[:image_size] : options[:image_size].to_s

could be simplified to:

image_size = options[:image_size].to_s

Since a String#to_s returns itself :)
