Title: settings.js: fix apparent typo in SettingsManager.unregister

Removing my Alt-Tab-Enhanced applet from the panel produces the following error output:
````

As far as I can tell, this is caused by an apparent typo introduced in commit 26e9b3dd: "this.instances" is only used once, and should most likely be "this.uuids"; by changing to the latter I can make the error go away.
