Deprecated method in lib/carrierwave/uploader/google_drive.rb

[vivitc]

Line 14: for the last versions, we use "update_attribute" instead of "update_column".
Given I have a project with ruby => '1.9.3p194', mongoid => '3.1.4' and I wanted to upload a file using carrierwave-google_drive. I got an error related to the deprecated method mentioned before.
