Fix consolidation plan to print relative paths in output (#4604)

This issue was found by @anastasop while testing Cloud support for
Consolidation plan. So far consolidation plan would print full URIs for
fragments. However, for remote arrays we should be only printing out
relative URIs. So, this fix replaces full with relative URIs for any
type of array consolidation plan.
