Package-tree in 'Knowledge Bases' panel may corrupt after they export/import a repository from BRMS 5.1.0 to 5.2.0.

You can reproduce it by:

- Start up BRMS 5.1.0 and install mortgages example
- 'Copy' mortgages package as 'newpackage' package
- Export the repository
- Start up BRMS 5.2.0
- Import the exported repository
- You will see duplicate 'mortgages' packages in package-tree

In BRMS 5.1.0, when you copy a package, the title of a new package would be just copied from the old title(= old package name).

org.drools.repository.RulesRepository

    public void copyPackage(String sourcePackageName,
                            String destPackageName) {
        PackageItem source = loadPackage( sourcePackageName );
        String sourcePath;

        try {
            sourcePath = source.getNode().getPath();

            String destPath = source.getNode().getParent().getPath() + "/" + destPackageName;
            if ( this.getAreaNode( RULE_PACKAGE_AREA ).hasNode( destPackageName ) ) {
                throw new RulesRepositoryException( "Destination already exists." );
            }
            this.session.getWorkspace().copy( sourcePath,
                                              destPath );

            PackageItem newPkg = loadPackage( destPackageName );

            for ( Iterator iter = newPkg.getAssets(); iter.hasNext(); ) {
                AssetItem as = (AssetItem) iter.next();
                as.updateStringProperty( destPackageName,
                                         AssetItem.PACKAGE_NAME_PROPERTY );
            }

            save();

        } catch ( RepositoryException e ) {
            log.error( e.getMessage(), e );
            throw new RulesRepositoryException( e );
        }

    }

# In BRMS 5.2.0, the title will be filled with the new package name

As long as you use BRMS 5.1.0, this is not a problem because PackageConfigData.name is filled with PackageItem.getName().

org.drools.guvnor.server.ServiceImplementation

    private PackageConfigData[] listPackages(boolean archive,
                                             RepositoryFilter filter) {
        List<PackageConfigData> result = new ArrayList<PackageConfigData>();
        PackageIterator pkgs = repository.listPackages();
        pkgs.setArchivedIterator( archive );
        while ( pkgs.hasNext() ) {
            PackageItem pkg = pkgs.next();

            PackageConfigData data = new PackageConfigData();
            data.uuid = pkg.getUUID();
            data.name = pkg.getName();
...
org.drools.repository.VersionableItem

        public String getName() {
                try {
                        return getVersionContentNode().getName();
                } catch (RepositoryException e) {
                        throw new RulesRepositoryException(e);
                }
        }

But In BRMS 5.2.0, PackageItem.getName() returns getTitle().

org.drools.repository.VersionableItem

    public String getName() {
        return getTitle();
    }

That is the cause of the corruption.
