Nick Lavers 5377fc6236 [SPARK-16961][CORE] Fixed off-by-one error that biased randomizeInPlace
JIRA issue link:
https://issues.apache.org/jira/browse/SPARK-16961

Changed one line of Utils.randomizeInPlace to allow elements to stay in place.

Created a unit test that runs a Pearson's chi squared test to determine whether the output diverges significantly from a uniform distribution.

Closes #14551 from nicklavers/SPARK-16961-randomizeInPlace.
