[DB] run all Forgejo migrations in integration tests
The tests at tests/integration/migration-test/migration_test.go will
not run any Forgejo migration when using the gitea-*.sql.gz files
because they do not contain a ForgejoVersion row which is interpreted
as a new Forgejo installation for which there is no need for migration.

Create a situation by which the ForgejoVersion table exists and has a
version of 0 in tests/integration/migration-test/forgejo-v1.19.0.*.sql.gz
thus ensuring all Forgejo migrations are run.

The forgejo*.sql.gz files do not have any Gitea related records, which
will be interpreted by the Gitea migrations as a new installation that
does not need any migration. As a consequence the migration tests run
when using forgejo-v1.19.0.*.sql.gz are exclusively about Forgejo
migrations.
