Improved management of online status from non-primary windows.

– The online status of the user should be checked and updated only
when the previous active window and the current active window both have
different sessions.
– Removed MainWindow::activeChangedHook since windows should not
change online status on their own on activating.
– Renamed Application::maybeActiveSession
to Application::maybePrimarySession.
– Added updating of online status on changing of the current account
since this seems to have been missed.
