Replace getPullRefName by Runtime.getPullRefPair

Browse Source 
This more or less reverts 9c9401a96c0b7d43dcea19c2972ef9612cc0a136
"Replace getPullRefPair with getPullRefName"; now that tests don't require
us to use pullRefName, move creation of storage references deeper into the
calls stack to reduce string use.

ir.getSinglePullRefNameGoal is accordingly updated to ir.getSinglePullRefPairGoal,
and we need to add a ~duplicate singlePullRefPairGoal; that duplication
of singlePullRefNameGoal will soon be resolved by dropping singlePullRefNameGoal.

Should not change behavior.
