With https://gitlab.com/gitlab-org/gitlab/-/merge_requests/32524 merged,
this should work now.

The reason for this lies in `initializers/fill_shards.rb`:

1. Before dropping 2018 migrations, table `shards` was not present in
the initial schema (with all migrations rolled back except the initial
one)
1. After dropping 2018 migrations, table `shards` is part of the initial
schema
1. Hence we run into `Gitlab::Database.read_only?`, which is dependent
on `geo_nodes`
1. `geo_nodes` has only been introduced with 20190402150158

Ultimately we should fix the initializer and not seed data through the
initializer anymore (this is making assumptions about the database,
which causes issues like here).

Migrations have been removed in a previous commit. Also remove their
specs here.

This removes migrations with a schema version number < 2019...

The effect of those migration is being folded into
db/migrate/20171230123729_init_schema.rb
