Getting rid of all the rspec deprecation warnings.

* the warnings were concerning usage of let/subject in before :all
* approach is to substitute them with instance variables/local
  vars
* not perfect but working for now, feel free to give feedback =)
* fixes #2
Correct the remote url as we don't have dynamic redirects anymore

* pointing directly to the S3 for now... like until we got a
  better solution
* improved error message when redirect limit is reached
