#4 The add module page is not invalidated if fields are empty

[Eduard Oajdea]

If the name and auto update interval are empty the page is not invalidated at add time and the module is not added.
Steps to reproduce:
1 Go to admin portal web page
2 Input valid values for username and password
3 Press the login button
4 Press the add module link
5 Leave the inputs empty
6 Select “Local” from the dropdown input
7 Press the add button
Expected result: the page is invalidated and the fields are marked as required.
Actual result: the module list is displayed and the module is not added.
