Fixed warning for YAML database header (#5843)

The wrong version was given when the database was not the latest version but was still compatible with the parser's minimum version.

Additionally only in cases of full incompatibility the file name was displayed. Added this as well so the file that needs an upgrade is known to the user. This has especially been a problem with empty import databases with outdated header versions.
