add case [in]sensitivity tests + add OfficialProvider model

`ci` in this context means "Case Insensitive".
`cs` in this context means "Case Sensitive".

New models created:
    - OfficialProvider
      This was required to write a test for checking that
      OfficialProviders behaves as we expect, which was the starter
      for the original aurblup bug.

New tests created:
    - test_official_provider

Modified tests:
    - test_package_base: add ci test
    - test_package: add ci test
    - test_session: add cs test
    - test_ssh_pub_key: add cs test
