[FIX] website_theme_install, base: fix theme update

When a theme module is updated the changes made on a view are considered
as user changes, prenventing the view from being updated in the future.

Fixed by comparing the arch being written with the arch of the original
view. If it is the same the record should not be noupdate.
Plus added a test to make sure the theme views receive theme updates
after being updated once.
