[EE] Dont persist application settings in test env bis
EE version of https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/8715
It's an autoloading issue where the EE
namespace wouldn't be defined prior to requiring EE::ApplicationSetting
. The first fix I made was to not eager-load Gitlab::ImportSources
(which turned out to end-up auto-loading EE::ApplicationSetting
twice before EE
would be properly defined, ending-up in an auto-loading issue, somehow.
This new fix simply defines the EE
module as soon as possible in the 1_settings.rb
initializer so that we avoid auto-loading issues properly.
