The `communityProfilePopup` relies on the currently `activeCommunity` to
get its data. Unfortunately, once read, even when `chatsModel.setActiveCommunity()`
is called which triggers `activeCommunityChanged`, the data in the popup
won't be updated. The next time one would open a community profile page,
it'd have the data that was previously received from the model.
This commit ensures that the popup is hydrated with the most recent data
by explicitly updating its properties right before it's opened.
