Performance tests time taken is wrong

[dlednik]

In this case it's a benchmark test.

It should report that it took 0.316s not 3.607 for the whole test

where 0.316 seconds is the average time for 10 passes this is a feature of the new XCTest framework with

measureBlock{ () -> Void in
}

Results output:

Test Case '-[RTiOSSDK_UnitTestsTests.GeometryEnginePerformanceTests testBenchmarkWithinOnSmallPolygon]' started.
