Marker position does not update when edited

[WillsB3]

When altering a markers location, the change is not reflected in the map. It seems as though the markers location is not watched.

See this example. Clicking the "Move a Marker" button should move the marker to a new random location.

The hack we've had to use to get this working is to use the doRebuildAll attribute to force the map to update. You can see this works by adding doRebuildAll="true" to the to the marker cluster element in the above Plunkr, but this solution is horrible...

Is this a bug in the clusterer?

Confirmed. I need to revisit this code in my PR as well. #948

Found the issue so when it gets to looking for updates it compares model to ChildModel.model, well they are somehow pointing to the same reference (not sure how they were not before). Anyway one ChildModel creation passing in a clone of model alleviates the problem.

As an alternative the model comparison could compare the model to a gObject. However this would require more code changes that are desired right now.

Confirmed that this happens as of 2.0.2. From that version on doRebuildAll needs to be set for the markers to move. Just did a bunch of manual testing to verify.

@grahamj yes it is confirmed with a PR fix

Along with specs to check it for now on.
