Bug 24697: Split items.uri on staff detail view

If there are more URIs, we split on vertical bar and show the real URL
instead of duplicated text. Otherwise display depends on the pref
URLLinkText.

Test plan:
Create item with uri = A | B | C
Create another item with uri = D
Check the results on staff detail view (items table).
