Move install-db-schema from afterReset to beforeAllMigrations

I believe this was handled by the `wipe-if-demo` script in the demo but I needed to manually run it in production since I removed that script from the `Procfile`. Not a huge deal but figured I would at least document it here to save someone else some time as it threw me for a little loop when I got the Postgres error.

Got the following error when I tried to register since the worker schema wasn't there

`Registration failed (Error code: ERR_3F000)`

Once I got the postgres logs running right on RDS it was fairly obvious, just had to run

`yarn workspace @app/worker install-db-schema`

and everything worked as intended
