Philip Rideout e99f13b14d Fix some RangeMap behavior and improve its unit test. ...

The existing unit test had an incorrect expectation in what happens
after splicing an existing range. Fixing the unit test revealed an
actual bug in the RangeMap implementation. It should never modify the
lower bound of an existing interval, because that invalidates the
iterator. It should also never retain a pointer or reference to a range
when the range is potentially removed by subsequent codelines.
