[FIX] web: unchecked radio button
[FIX] web: unchecked radio button

Before rendering the radio button, the radio button must be unchecked
to ensure to take the last value checked.

Step to reproduce:

-From main menu, click on 'Contacts'
-Click on 'Create'
-Select 'Company' value on company_type field
-Save or not the contact
-Return in the main contact view (click on breadcrumbs)
-Click on 'Create'

Bug:

The default value on company_type field is 'Company'
but the fields that should be hidden are visible (example : parent_id field)

After the fix:

The value of company_type field is 'individual'
