[Bug] Issue when the class from a custom namespace has been declared as an array type.

The namespace from the original source code is getting replaced with some invalid namespace when we declare the class as an array type.

Input:
```com.ibm.ws.webservices.engine.description.ParameterDesc[] _params0 = new com.ibm.ws.webservices.engine.description.ParameterDesc[] {};```

Actual:
```_class_pkgname_ _params0 = new org.jboss.axis.description.ParameterDesc[] {};```

Expected:
```com.ibm.ws.webservices.engine.description.ParameterDesc[] _params0 = new org.jboss.axis.description.ParameterDesc[] {};```

Note:
We are using snipper pretty printer from spoon.

* OS: Windows 10
* JDK: 11
* Spoon version: 10.0.1
