AADL Navigator: New AADL package is not inserted in correct order

[lwrage]

Summary

Creating a new AADL package inserts it as the first element in the project.

Expected and Current Behavior

The common navigator framework tries to insert the new package in the correct location but our sorters seem to be wrong. We currently refresh the navigator (see #1608) to force sorting but this is not the correct solution.

Environment

• OSATE Version: 2.3.6
• Operating System: all

Check if setting parent fixes the issue.
