This initializer wasn't actually checking the exact conversion. Corrects the tests as well.

It looks like this test failure is because bridging from NSNumber back to Double calls Double.init(exactly:). This used to succeed for large values like UInt.max, but now doesn't. I suppose we can just opt out of the Float/Double tests for values that are too large—would that be an okay fix for this? The Int bridging tests don't test floating point conversions at all.

@natecook1000 I do believe that there were some patches, at least in swift-corelibs-foundation, addressing the issue of NSNumber exact bridging. I'm hazy on the conclusion but it'd be unfortunate if fixing Double.init(exactly:) broke the agreed-upon semantics for NSNumber bridging.
