Previously, .simplecov called `SimpleCov.result` to store the coverage result, and ignored the return value. `SimpleCov.result`'s return can be slow to calculate, which wastes a lot of time when it's ignored. This commit extracts the code needed to store the SimpleCov result from `SimpleCov.result`, and calls it directly, without doing the busywork to compute the return value every time. In my testing, this more than halves the time taken to run all the integration tests.
