Fix UI test hang: remove ad-hoc signature before test launch

Browse source 
The Mac Mini runner has no dev certificates, so xcodebuild produces
an ad-hoc signed app. Gatekeeper rejects it, causing XCUITest to hang
forever at app.launch(). Split build and test phases, strip the ad-hoc
signature between them so the app can launch.
