Shams Asari f52d158f2d CORDA-2665: Updated OwnableState relevancy check put back to V3 version ()
* CORDA-2665: Updated OwnableState relevancy check is now gated on target version 4

https://github.com/corda/corda/pull/3789 changed the relevancy check of OwnableState to include the participants list in addition to the owner. This however breaks existing apps which assume (in their vault query) an OwnableState is recorded to the vault if-and-only-if the owner matches.

* CORDA-2665 Don't switch to new behaviour on target version upgrade.
