Fix Update function on details page.

The problem was that parameters with no values are automatically
set to None by the framework and it wasn't handled properly in
baseldap.py:get_attributes function. Also, there were two logical
bugs in details.js:
1) atttribute callback to update values were called for input elements
   instead of dt elements
2) it was always trying to update the primary key
