Updated printed details of run-test action.

Before that commit we were printing next run-test details:

    run-test TestProject-LibraryTests.octest (iphonesimulator8.0, logic-test)

Those details could be wrong because actual simulator version is defined by `-destination` flag if so is provided and not by `Xcode_SDK_NAME` in build settings.

This commit respects `-destination` argument and prints actual arguments used to launch simulator:

     run-test TestProject-LibraryTests.octest (7.1, iPhone 5s, logic-test)
