[FIX] web: NotificationManager: warnings style

Warnings are styled a bit differently than notifications, as their
background is red (thanks to classname 'o_error' on the warning
root element). This classname isn't correctly added since rev.
920df59, which changed the root element of the 'Notification'
template, which is extended by the 'Warning' template, making
qweb.js fail to add the 'o_error' classname.
