Default 'closed' investment accounts as unselected in the Investment pages (edited)
Much like how closed accounts are hidden elsewhere (with that option selected) they should not be selected by default when going to the Investments area.
Investments - Balances: Minimal harm in it being here, but its a worthless row of data and worthless line on the chart when closed accounts are always set to a zero balance
Investments - Performance: Much more annoying. Having it included results in a warning every single time you visit the screen due to "insufficient data" around the performance of that account. And deselecting it still results in it being selected again the next time you visit the screen. And if you actually do have a problem with insufficient data on an active account there is a good chance you won't even notice it because you're numb to always seeing that warning on this screen.
