Mark XCTest suites as passed/failed immediately on suite completion

Add back some code that was removed that marked XCTest suites as
passed/failed as soon as all their tests completed. Currently the
TestExplorer shows the test suites as pending until all tests in the
whole test run have completed. This is a regression from how the Test
Explorer used to work, where suites were marked as passed/failed
immediately upon suite completion.

Issue: #1029
