I write a migration plan for my process instances.
We did not set a versionTag in the beginning, so I have several old instances running with null for the version tag.
The new target definition comes with version tag 1.
To build a migration plan, I need the sourceProcessDefinitionIds of all instances running on a versionTag equal to null.
However, I can not query for those definitions, because a query parameter null is not allowed for versionTag.
Since having a null version tag is common, allow querying for it with a new query method withoutVersionTag.
