Fix warnings

[spickermann]

Should remove these warnings:

gems/zaikio-directory-0.0.7/lib/zaikio/error.rb:8: warning: already initialized constant Spyke::ConnectionError
gems/spyke-5.3.4/lib/spyke/exceptions.rb:3: warning: previous definition of ConnectionError was here
gems/zaikio-directory-0.0.7/lib/zaikio/error.rb:9: warning: already initialized constant Spyke::ResourceNotFound
gems/spyke-5.3.4/lib/spyke/exceptions.rb:2: warning: previous definition of ResourceNotFound was here

Feel free to merge and push to Rubygems. Btw you might want to:

gem owner zaikio-directory -a [email protected]
gem owner zaikio-jwt_auth -a [email protected]

Thanks for taking the initiative! I will have also a closer look!
