Use of alias_method_chain has been depreciated in Rails 5

[jorroll]

This is my first time using Github / commenting on a project, so forgive me if I've made a mistake, but while upgrading my Rails 4.2 app to Rails 5, I've encountered a depreciation warning related to activerecord-import's use of alias_method_chain found in lib > activerecord-import.rb.

As detailed here in Riding on Rails, and here in this Rails pull request 19434, alias_method_chain has been depreciated in favor of Module.prepend. I've looked into offering up a fix using Module.prepend, but I'm afraid I'm just not knowledgeable enough in Ruby.

Thanks for reporting this @thefliik. I've known about this for a while, but I've ignored it since alias_method_chain is so much more readable than trying to follow Module#prepend.
