Bug 234973 - Make selected row visible after removing/editing entries in password manager. r=Dolske

Added a call to
'treeBoxObject.ensureRowIsVisible(signonsTree.view.selection.currentIndex)' in
'signonReloadDisplay()' to make sure the selection is visible regardless of the
operation which caused a call to signonReloadDisplay().
