Description
Hi,
I was trying to update OrientDB to TinkerPop 3.7.0, and I got some test failing, with some debugging I noticed that the `DetachedVertexProperty` implement equals for the property, but inherit the hashCode from `DetachedElement` that it does not behave as a property but as an element. It may be there also other `VertextProperty` that do not implement correctly the hashCode.
Adding a simple example patch in attachment.
here is the branch I'm working on for the update https://github.com/orientechnologies/orientdb-gremlin/tree/WIP_update_deps I do have additional tests failing to check
