[SPARK-13254][SQL] Fix planning of TakeOrderedAndProject operator
The patch for SPARK-8964 ("use Exchange to perform shuffle in Limit" / #7334) inadvertently broke the planning of the TakeOrderedAndProject operator: because ReturnAnswer was the new root of the query plan, the TakeOrderedAndProject rule was unable to match before BasicOperators.
This patch fixes this by moving the `TakeOrderedAndCollect` and `CollectLimit` rules into the same strategy.
In addition, I made changes to the TakeOrderedAndProject operator in order to make its `doExecute()` method lazy and added a new TakeOrderedAndProjectSuite which tests the new code path.
/cc davies and marmbrus for review.
