fix: Handle undefined DashboardData props

[bmingles]

• Handle undefined props on DashboardData. Don't render console panel if no session
• Fixed a set state on unmounted HeapUsage bug
• Removed chatty async interval debug logging

fixes #1684

Testing

• Run server with PSK enabled
• Login and open any file
• Logout should no longer show "ConsolePanel.tsx:372 Uncaught TypeError: Cannot destructure property 'config' of 'sessionWrapper' as it is undefined." error in debug console (Note that login will still fail until Open file blocks logout #1685 is done)

getDashboardSessionWrapper currently only returns SessionWrapper - that needs to be updated to allow undefined as well.
