Before this commit, a field selection which was required
did not have an empty option
ref: 4dfabb8f7a
This is fine, but overlooked the fact that modules can modify
the required attribute, or even views can do it
So, we may end up in a situation where the field is required but set to false
This configuration is problematic, at least for the timezone selection field
(see OPW)
After this commit, the empty option is just not visible
note that `disabled = True` would not work because val is not accessible
Because of commits:
- 4dfabb8f7a for the selection feature
- d77ce4c2a9 overriding the required attribute of tz in res.user form
