Bug 13605 - _AUTHOR_ not replaced in relatives checkouts

Bug 13605 - _AUTHOR_ not replaced in relatives checkouts

In members/moremember.pl, in relatives checkouts tab, "by _AUTHOR_" appears before author.
This code sould be replaced in JS.

Test plan :
- Go to a borrower with relative's checkouts
=> without patch : you see "by _AUTHOR_" string before author name
=> with patch : you see "by" string before author name
