Title: MODE-2124 Changed the code so that child node re-indexing (on update of the parent) is only performed when the path of the parent has changed. 

Also, based on additional CPU usage profiling, removed a `String.intern` call.

@rhauch: after fixing the indexing issue, additional profiling showed a significant hot-spot in an `intern` call
