LP#1738249: Item status column picker fixes

Adds some fixes to the column pickers in the web staff client Item Status
interface:

  * The Circulation Library field now displays the asset.copy circ library
    instead of the checkout library.
  * The Circulation Library and Checkout / Renewal Library now show the
    shortname instead of the full name.
  * A typo fix so that Remaining Renewals display
