Manually update badge count in initActiveConnection

Without doing this, it's possible to start NeoChat and have no badge
count despite having notable notifications. The reason for this is if
badgeNotificationCount was updated and changed before this function
call, and a call to refreshBadgeNotificationCount doesn't emit the
changed signal.

This is easy to work around by calling updateBadgeNotificationCount
ourselves.
