Online results changes should be watched (and shown) even when not at the results screen

[peppy]

Currently, we have a flow for watching for statistics changes of the logged in user, but it's only acted on if the user remains at the results screen. This isn't always the case, as users regularly leave the results screen before processing completes. In such a case, two things go wrong:

• They won't be aware of the change in statistics (in stable this is shown in a very jank way, with numbers appearing in the middle of nowhere, but it is shown and people are used to seeing it)
• Because the stats aren't updated, when they play the next beatmap it will include the difference in stats from the previous play, resulting in incorrectly high numbers. This was reported in private testing as "a loved map gave me pp" or similar.
