Fix saving search containing slash ('/') character

Steps to reproduce:

Scenario 1:

1. Navigate to Search menu in the left panel
2. Create Search by entering any text
3. Now click on Save AS
4. Enter the saved search name in the  “Save Search” modal using slash( 
   /) operator and click on Save

The popup modal stays up and no error is displayed.  Checking the browser console shows the following error:

Resource request failed: java.lang.IllegalArgumentException: Invalid name 'test10/new'. A DocumentModel's name cannot contain slash character. Use the parentPath to specificy the document's path.

 

And the following is shown in the response:

{"entity-type":"exception","status":400,"message":"java.lang.IllegalArgumentException: Invalid name 'test10/new'. A DocumentModel's name cannot contain slash character. Use the parentPath to specificy the document's path."}

 

Expected Behavior:

Either an error is shown saying that a '/' is not allowed in the saved search name or the search is successfully saved.
