Sails failed to lower / process does not exit - cannot destroy mysql connection pool

**Sails version**: 1.1.0
**Node version**: 10.15.0
**NPM version**: 6.7.0
**DB adapter name**: sails-mysql
**DB adapter version**: 1.0.1
**Operating system**: mac os 10.14

When calling sails.lower(); the process is getting stuck in a loop trying to destroy the MySQL connection pool. Im not sure what could be causing this, any Ideas would be extremely helpful.

```
"use strict";

var sails = require('sails');

sails.lift({
log: { level: 'silly' }
}, (err) => {
if (err) throw err;
console.log("Sails Lifted");
sails.lower();
});
```

Start with the reproduced sails.lift() callback and sails.lower() call, then trace the teardown stack through sails-mysql/helpers/teardown.js and sails-mysql/helpers/private/connection/destroy-manager.js into machinepack-mysql/lib/destroy-manager.js. Reproduce the Quit inactivity timeout and verify that lowering the lifted app destroys the MySQL pool and lets the process exit.
