Sentry UI Lifecycle breadcrumbs produce some non-intuitive results

[nbrooke]

The automatic UI lifecycle breadcrumbs that Sentry produces seems to not always give great results when popups (and view controller containment?) are involved. For example, in Spies, almost any in-game crash or error is attributed to "CityDialogViewController", because it was often the last new view controller that was presented, even though it's generally been dismissed well before the actual problem happened.

We should see if there is something we can do to to make those results more reflective of what the actual state of the UI is currently.
