Delete does not completely remove references to the deleted project.

### Apache NetBeans version

Apache NetBeans 23

### What happened

I created a new "Musician" project "Java with Ant" -> "Java Enterprise" -> "Enterprise Application Client", adding it with "Add to Enterprise Application" to an Ant Enterprise Application "Orchestra". Deleting afterwards the project "Musician", with the option "Also delete sources" does not remove all references to "Musician" from the following files: project.xml and project.properties. The directory ot the "Musician" project was correctly deleted.

project.xml after deleting the "Musician" project:

```xml

org.netbeans.modules.j2ee.earproject


Orchestra
1.6.5



${reference.Orchestra-war.dist-ear}
/


${reference.Orchestra-ejb.dist-ear}
/

**
${reference.Musician.j2ee-module-car}

### Language / Project Type / NetBeans Component

Java / Ant Enterprise Application Client / Jakarta 10

### How to reproduce

Create an Ant Java Enterprise Application. Add to it an Ant Java Enterprise Application Client. Then, delete the brand new Java Enterprise Application Client. You will find the old references to the deleted client project in some files like project.xml and project.properties.

```xml

org.netbeans.modules.j2ee.earproject


Orchestra
1.6.5



${reference.Orchestra-war.dist-ear}
/


${reference.Orchestra-ejb.dist-ear}
/


${reference.Musician.j2ee-module-car}
/

No

Reproduce the deletion flow in Apache NetBeans 23 using an Ant Enterprise Application and an Enterprise Application Client. Inspect the generated project.xml and project.properties after deleting the client, focusing on the remaining references to Musician. Done means the deleted project's library, project reference, and related properties are removed without affecting the remaining modules.
