What you are doing?

Using Sequelize with Sqlite.

What do you expect to happen?

I want the connection with Sqlite to be closed properly and the file *shm and *wal deleted.

What is actually happening?

*shm and *wal files persist after termination of the process.

__Dialect: sqlite
__Database version: 3.1.6
__Sequelize version: 3.24

A PR would be accepted? I would implement disconnect() in the sqlite connection manager. disconnect() would call close() on all this.connections
