ShellListView_Navigated: Commented more code

Commented out the code because it did not seem to have ANY effect

It is likely that SetUpStatusBarOnSelectOrNavigate(...) is already be is
already being called from ShellListView_SelectionChanged(...)
Removed IsSelectionRized

It was never anything but [false] and I do not see any way the method
would call itself again before it was finished the first time and thus
making it true
