Spring Data Cassandra tests are using the wrong property for customizing the repository type

[snicoll]

It's using spring.cassandra.repositories.type instead of spring.data.cassandra.repositories.type.

Hi @snicoll, I'd like to pick this.

@krutip7 thanks but that's not just about renaming the property, we need also to make sure it's testing the right thing. Given that the property was wrong, so are the tests.
