A parent and child classes having private property fields with the same name fail to be synchronized

[rbi]

HOW TO REPRODUCE

• given the following classes:

class A {
  private StringProperty propertySameName = new SimpleStringProperty();
}

class B extends A {
  private StringProperty propertySameName = new SimpleStringProperty();
}

• Synchronize objects of them and change the value of both private Properties.

WHAT HAPPENED

• An Exception is thrown:

de.saxsys.synchronizefx.core.exceptions.ObjectToIdMappingException: An object with the id [d44b9948-98db-4b53-935e-5156fe46ab71] was expected to be known but it was not.  In most cases this means that synchronism with other peers has been lost.

WHAT SHOULD HAPPEN

• No exception is thrown
• both properties have the correct value.
