New renaming API did not work for some subclasses of AbstractItem (JENKINS-52164)
Merged https://github.com/jenkinsci/cloudbees-folder-plugin/pull/120 for AbstractFolder.isNameEditable.
PCT Fix DefaultModelTest#shouldBePossibleToRenameTemplates (CPLT2-5978)
The Templates feature had not been updated to match recent Jenkins changes in item renaming: there was an old rename UI (editing Name in Configure) in addition to the new UI (Rename link); and renaming templates did not work (an error was thrown).
The UI for renaming both templates and templatized jobs/folders is now updated to the current Jenkins standards.
