Revert "added isReallyNew() method to allow differentiating between newly-instantiated and newly-created documents — backbone.js internal isNew() mechanism was no good here since Backbone.Drowsy uses client-generated document ids"

This reverts commit 98c3bbb7a26c3ac760369cc242cc8e205177f1ac.
isReallyNew was a bad idea..... extended timeout to 35 seconds to match WakefulWeasel's 30
