Fix "cannot set headers after sent" in setting doc end point

Browse source 
If somehow a project ends up with the same doc/file in two locations in the
file tree, then projectLocator.findElement will return the callback for
both entries. This then tries to end the request multiple times. Of course
this should never be a state the project is in, but if it is we should catch it.
