    Return 404 to ajax environment update table call

    Before a 404 exception from api was not properly handled and
    returned 500 error to dashboard ajax call. This resulted in a deleteing
    environment row being stuck until page reload.

    Thi patch throws django Http404 in case the row has been deleted
    successfully and let's other exception to be handled by the universal
    handler. Also updates the handler to work with non-deprecated version of
    exceptions from api calls.
