Fix failing check-migrations CI check

[NevilleS]

Overview

As a result of #700, the automated check-migrations check is failing, but this appears to be a false positive. The check itself fails, as if a migration is missing and needed, but when you go to actually generate a migration nothing is created since the schema is fully complete.

Therefore, this is a bug with the check-migrations check, so we'd like to find a better workaround for this.
