Restore Fog.credentials[_path] after test
Restore Fog.credentials[_path] after test

Store the original values of Fog.credentials and Fog.credentials_path and
restore them after the test. This will prevent this test from rendering Fog
unusable for any tests that follow it.

It can be verified by placing the following at the end of the spec file:

    describe 'after' do
      it { expect(Fog.credentials).to_not eq({}) }
    end
