[FIX] web, website: start public widgets after all lazy loadings

Bug introduced with
https://github.com/odoo/odoo/commit/1f5c9e363b6f7cb9a2770e6247536803fd13e3f0

Before this commit, the public/website root was started as soon as
the bundle it is in was lazy loaded. It then started all the registered
public widgets. The problem was that some of those may be registered
by other lazy-loaded bundles. The public root would then not start
those if those bundles were lazy-loaded with a too long delay.

This commit fixes the bug by starting the public/website root once all
known bundles are fully lazy-loaded.
