On 19.0+, test that demo data load correctly

[sbidoul]

Since tests do not load demo data in Odoo 19.0, we may need a separate CI step to verify that demo data are valid.

Is there a smarter way to do this than adding a new CI job that does just that?

Reusing an existing test pipeline seems a source of problems due to conflicts between this demo data and data created by the tests. I'm afraid there's no better way, but an installation with the demo flag and without tests can be quick enough.

I'm thinking that runboat may load that demo data, and then gives error if not possible, so we have 2 benefits. Having instances with demo data for testing, and detecting these problems.

I thought about that too, but currently runboat is basically always green, as if it can't load modules, it is happy with creating a db with the base module only. This is by design to have something functioning in case there are incompatible modules in the repo.
