Sequelize v7 issue

[axeldvp]

Since sequelize updated to v7.0.0-alpha.40 rate limiter does not work.

Everything was working fine until v7.0.0-alpha.39.

Error: Accessing the connection manager is unlikely to be necessary anymore.
If you need to access the pool, you can access it directly through `sequelize.pool`.
If you really need to access the connection manager, access it through `sequelize.dialect.connectionManager`.
