tablePerHierarchy = false ignored when extending an abstract entity class

When trying to get DevTeamEntity from database, I get
`org.h2.jdbc.JdbcSQLSyntaxErrorException: Column "MEN0_.CLASS" not found; SQL statement:`
even though I've specified tablePerHierarchy false
```
abstract class MasterEntity implements Identifiable {
Long id
static constraints = {
}
}
```

```
class PersonEntity extends MasterEntity {
Long weight
static mapping = {
tablePerHierarchy false
}
}
```

```
class ManEntity extends PersonEntity {
String firstName
String lastName
DevTeamEntity devTeamEntity
}
```

```
class DevTeamEntity {
Long id
static hasMany = [
men: ManEntity
]
}

```

```

Start by reproducing the reported query with MasterEntity, PersonEntity, ManEntity, and DevTeamEntity, focusing on the tablePerHierarchy mapping and the generated SQL shown in the report. No repository file or test is identified, so locate the relevant inheritance-mapping tests or entry points before making changes. Done means loading DevTeamEntity no longer queries a missing CLASS column.
