Bug 25583: Disable the "claim returned" button if the feature is disabled

It's possible to display the "Return claims" column on the checkout
list, even if the feature is disabled.
We should disable the link and add an explanation.

Test plan:
- Make sure ClaimReturnedLostValue is empty
- Go to a patron account
- Check out an item
- Make the claims returned column visible in the table of checkouts
=> The button is disabled and a tooltip explains that the feature is
disabled
