XMLRPC wp.getPageList and auto-draft pages broken dates

[skithund]

XMLRPC wp.getPageList method returns all pages, including auto-draft ones.

auto-draft pages have post_date_gmt date as '0000-00-00 00:00:00', resulting in invalid dates in XMLRPC reply.

<name>date_created_gmt</name>
<value><dateTime.iso8601>-0001113TT0::0::00</dateTime.iso8601></value>

Remove auto-drafts from wp.getPageList method or fix post_date_gmt somehow.

Closed this as duplicate of #19733. That fixed the date issue in 3.4
