Notebook's not loading if one of the notename contains '/'


It will have a exception : 

TypeError: Cannot read property 'length' of null
    at e (noteList.datafactory.js:49)
    at noteList.datafactory.js:41

Workaround : Rename the note  with name '/'

Root cause :

 var nodes = noteName.match(/([^\/][^\/]*)/g);

when we are trying to match the parent and child notes with regex expression in 
javascript its failing with no match as the name itself is '/'


attached screenshot of the issue.
