fix: Existing Hooks are replaced with new ones on restart

[cbaker6]

• When ParseServerSwift starts, it will 1) detect if a hook already exists on a node ParseServer, 2) delete the current hook 3) create a new hook. This prevents the node ParseServer from accidentally using a stale hook and polluting the Dashboard with multiple versions of the same hook
