Viewer handler keeps reference to Navigator

See original GitHub issue

https://github.com/openseadragon/openseadragon/blob/3bbfbcbc0e136405e3f8ed95316d36255dba835f/src/navigator.js#L399

My project has 2 active navigators. One is regular navigator that shows everything. The other is navigator for the current image that user is viewing.

My project has custom logic that detect when user is viewing an image at a particular zoom level and creates a navigator for it by viewer.slidesNavigator = new OpenSeadragon.Navigator(options);

By taking memory snapshots, we found that handlers in the main viewer keeps a reference navigators that are no longer in use.

Thus the navigator will never be garbage collected
