Fix for new thread submission

Created a fix to the issue where on submitting a new thread, the editor
exiting alert is fired. A new optional attribute was added to the editor
so that the controller can notify the directive that the user is now
submitting the editor content and is being redirected. This notification
turns off the editor exiting alert on the editor side.
Removed unnecessary console logs

Removed unnecessary console logs in the editor directive.
Editor exit/leaving function on error

Edited the editor exiting and leaving function setup so that it can
handle the case where an error occurs and the exiting/leaving functions
are put back into place.
