Title: LPS-25081

While there's nothing native to Liferay 5.2.3 which creates the problem where DLFileVersions exist for some DLFileEntries but not others, since the resulting situation is identical to what we need to deal with in LPS-25844, the same fix of checking for whether a DLFileVersion already exists will also fix this issue.
