**Steps to reproduce**
1. Use Page Curation to nominate a new page for deletion (AfD).
1. Repeat step #1.
Page Curation adds the AfD text to the same page, even though it already exists.
Page Curation should create a new AfD page, appending to the title //(2nd nomination)// or //(3rd nomination)//, etc., based on what AfD pages already exist.
For instance, if "Foobar" is nominated for deletion, the page //Wikipedia:Articles_for_deletion/Foobar// is created. The next time it is nominated for deletion (say, the first AfD resulted in a "keep"), Page Curation should create //Wikipedia:Articles_for_deletion/Foobar_(2nd_nomination)//.
See [[https://en.wikipedia.org/wiki/Wikipedia:Articles_for_deletion/Queen_Street_Bus_Terminal|Wikipedia:Articles for deletion/Queen Street Bus Terminal]] for example. The page [[https://en.wikipedia.org/wiki/Queen_Street_Bus_Terminal|Queen Street Bus Terminal]] was nominated by Atsme. If the first deletion discussion page already exists, page curation should add text to the appropriate discussion page instead (i.e. with "2nd nomination", "3rd nomination", etc. in parentheses suffixed to the end of the title) for consistency with Twinkle.
