LP1845241: Use the correct API call to Undelete a bib record

To test:

1) Open up a delete-ready bibliographic record in the Web client
(no attached holdings, no located URI, no open orders attached, etc.)
2) Delete it.
3) Undelete it.  Note that the "Undelete" button briefly turns into a
"Delete" button before changing back to an "Undelete" button.  Note that
the bib record does not show up in search results within the Web client.
4) Apply this commit.
5) Now try undeleting the record again.  Notice that the "Delete" button
does not revert to an "Undelete" button.  Note also that the record is
once again showing up in search results (although you may have to be a
bit creative using search terms, due to search results caching).
