Issue Description

Found during #314, when testing multiple targets with multi_scan and there are failed tests, the summary data for the failed tests is incorrect.

Notice how it uses the names of all targets as the target name for the test identifiers:

failed_tests | ["TestTarget1.xctest, TestTarget2.xctest, TestTarget3/TestTarget1Tests/testTarget1Test", "TestTarget1.xctest,TestTarget2.xctest, TestTarget3/TestTarget2Tests/testTarget2Test"] 

Complete output when running fastlane, including the stack trace and command used
