Somehow, having theses 2 new `website.page` records created separately from
their `ir.ui.view` would throw an error in dev-xml when installing website
module.
A task has been created in website team to track the origin of this bug.
In the meantime, this commit will avoid the traceback by creating the view
inside the page record. As the page's view is not intented to be inherited, it
is the best way to write it anyway.
