upgrader: upgrade catalog schema right after installing BTs

93e30e5e introduce a  new `user` table that is listed as a *search table*, so until this table is created all catalog queries are failing, and alarm tool, which relies on catalog fail with such a traceback:

```

This means that even if upgrader's post upgrade constraint are supposed to fix this by calling `portal_catalog.upgradeSchema`, because this constraint rely on alarm tool, it's already too late.

The suggested way to fix this is to also call [`portal_catalog.upgradeSchema`](https://lab.nexedi.com/nexedi/erp5/blob/c99fb9163503c5afdef59ecb124b3060b05330a4/bt5/erp5_upgrader/SkinTemplateItem/portal_skins/erp5_upgrader/TemplateTool_checkTableConsistency.py#L7) in the same transaction that the transaction upgrading business templates.

I have not completely removed `TemplateToolTableConsistencyConstraint`, because maybe there will be cases where just call post upgrade alarm to execute data migration steps after installing a business template manually. But you guys think it's better to completely merge `TemplateToolTableConsistencyConstraint` with `TemplateToolBusinessTemplateInstallationConstraint` I would be OK with that too.

Of course, we cannot just make
`TemplateToolTableConsistencyConstraint` an `upgrade` constraint, because there would be no guarantee that it's called after `TemplateToolBusinessTemplateInstallationConstraint`.

Also, I have not considered making [`getColumnMap` and friends](https://lab.nexedi.com/nexedi/erp5/blob/master/product/ZSQLCatalog/SQLCatalog.py#L1142) resilient to the case where a table listed in search tables does not exist, because it's would just have been failing later anyway and it's better to fail early in such case.
