Do not save an initial revision for a post created through the auto-draft mechanism. Prevents a bogus revision, often with the title 'Auto Draft'. Restores pre-auto-draft behavior made obvious by XML-RPC's implementation of both auto-drafts and the subsequent wp.getRevisions method. fixes #22687. see #22686.
