Stop the first-run seed carrying one company's tools

A build gets sent to testers, and this one arrived with the apps it was
developed against baked in as defaults - including an internal Odoo
hostname and a per-person Google account index in every path. Nothing
personal ships inside the bundle, but the seed is compiled into it.

The seed is now three generic Google apps that link to each other, which
is enough for a tester to see app switching work without learning where
anyone works.

A test asserts it stays that way: every seeded URL must be a plain
google.com host with no account index. It would otherwise drift back the
next time the seed is edited for convenience.
