What's going on here is that we're calling BrowserToolbar's onTabChanged method is calling refresh() when it gets a LOCATION_CHANGE event, and that's asking the tab about its current title, but we weren't clearing the tab's title before firing that LOCATION_CHANGE event.

I don't think we actually need to be calling setTitle on LOCATION_CHANGE, since we seem to also be getting a TITLE event for that change, but it seems messy to try to split apart refresh().

[Approval Request Comment]
Bug caused by (feature/regressing bug #): n/a
User impact if declined: old page title briefly flashes before a new page is loaded (can look pretty bad on slow connections)
Testing completed (on m-c, etc.): just landed on inbound
Risk to taking this patch (and alternatives if risky): low-risk, a clean-up call that got missed in the original implementation of the location change handler
String or UUID changes made by this patch: n/a
