Neat dms connections reverse 004

Validates that the container referenced by the reverse connection source properties exist.

What it does

Checks that the container holding the direct connection property (used in reverse connection) exists.

Why is this bad?

The direct connection property must be stored in a container. If the container doesn't exist, the connection cannot be persisted.

Example

If WindTurbine.windFarm maps to container WindTurbine, but this container doesn't exist, the reverse connection from WindFarm cannot function.
