 ticket: 5782

 When Network Identity Manager starts, the credentials display
 enumerates known identities and displays them if necessary.  However,
 as plug-ins load and the list of known identities, their properties
 and credentials change, the order of the displayed list will also
 change.

 The existing code does not deal well in respect to tracking the
 current selection when the list of identities and credentials change.
 This results in inconsistent behavior where the identity that was
 originally at the top of the list maintains its selection state while
 the identity at the top of the list after all the plug-ins have loaded
 will receive focus.

 This patch fixes this problem by explicitly setting focus and
 selection to the identity or credential at the current cursor location
 following a change in the credentials list.
