When a brand new Decidim app is generated the following tables are created:

this tables are reminiscences from when Forms were part of Surveys.

In old installations admins should destroy this tables when its content is migrated into the Forms module.

But for new installations there's no need to have these tables from Surveys.

Describe the solution you'd like

Remove the form related migrations that still exist in decidim-surveys. So that they are not created in new instances.
