In the case where an error is thrown in the UI before initialization has finished, we aren't capturing the application state correctly for Sentry errors. We had a test case for this, but the test case was broken due to a mistake in how the `network-store` was setup (it was not matching the behavior of the real `local-tstore` module). The pre-initialization state capture logic was updated to rely solely upon the `localStore` instance used by Sentry to determine whether the user had opted-in to metrics or not. This simplifies the logic a great deal, removing the need for the `getMostRecentPersistedState` state hook. It also ensures that state is captured corretly pre- initialization in both the background and UI.
