version property injected and considered a persistentProperty regardless of version mapping

[zyro23]

• Steps to reproduce provided
• Stacktrace (if present) provided
• Example that reproduces the problem uploaded to Github
• Full description of the issue provided (see below)

Steps to Reproduce

1. define a domain class Dummy with

static mapping = {
    version false
}

2. try to access new Dummy().version or check the entities' persistentProperties

Expected Behaviour

no version property is injected because of version false

Actual Behaviour

• a version property is injected and considered a persistent property.
• GormEntityTransformation seems to injected it regardless of the verison mapping: https://github.com/grails/grails-data-mapping/blob/v6.1.10/grails-datastore-gorm/src/main/groovy/org/grails/compiler/gorm/GormEntityTransformation.groovy#L447-L454
• but PersistentEntity.isVersioned() returns false
• the actual db column is not created

Environment Information

• Operating System: win x64
• GORM Version: 6.1.10
• Grails Version (if using Grails): 3.3.6
• JDK Version: oracle 8u151

Example Application

sample app will be referenced asap

We are aware of this issue, unfortunately due to how the transform works it is not easy to fix
