"Sessions do not time out" is always unchecked on edit user form

[edmundoa]

Problem description

On 2.0.1, editing a user that had previously checked the "Sessions do not time out" checkbox, will show that checkbox unchecked. It is only a cosmetic issue: the preference is correctly saved, and also the state of the session time out controls (those that let you select when the session times out) is also right, as the inputs are disabled.

Steps to reproduce the problem

1. Go to the edit form for a user
2. Check the "Sessions do not time out" checkbox, and save the changes
3. Do a full reload (just to be sure)
4. See that the "Sessions do not time out" is unchecked
