Programmatically setting an assoc def's "Include in Label" flag throws exception

[jri]

When trying this:

dm4.getTopicType("...").getAssocDef("...").getChildTopics().set("dm4.core.include_in_label", false);

a ClassCastException is thrown:

Caused by: java.lang.ClassCastException: de.deepamehta.core.impl.AssociationModelImpl cannot be cast to de.deepamehta.core.model.AssociationDefinitionModel

Thanks to Robert for reporting!

Add test to illustrate another problem with #1062.

In conjunction with the progress in #1063 this works now:

assocDef.getChildTopics().set("dm4.core.include_in_label", true)

BUT only if no custom assoc type is set for the assoc def.
This is illustrated by the new test.

See #1062.

Core: fix setting "Include in Label" (#1062).

Setting an assoc def's "Include in Label" flag works also if a custom assoc type is set for the assoc def:

assocDef.getChildTopics().set("dm4.core.include_in_label", true)

See #1062.
