Wrong behavior in scheme generator

[happiness9721]

I'm using xcake with the Cakefile below in Xcode 9.2

project.class_prefix = "APP"
application_for :ios, 8.0 do |target|
    target.name = "YourApp"
    target.all_configurations.each { |c| c.product_bundle_identifier = "com.yourcompany.yourapp"}
    unit_tests_for target
    ui_tests_for target
end

it generate redundant UITest scheme like below
