Global namespace dependecies are resolved invalidly within other namespaces

[montoriusz]

Namespace name (and package name) of any global namespace class (like SplObjectStorage in the following examples) is resolved to an empty string.

namespace EcAnalytic\Tables;

use SplObjectStorage;

class QueryBuilder implements IQueryBuilder {

    protected function buildQuery() {
        $this->exprToCol = new SplObjectStorage();
        $this->joins = new SplObjectStorage();
    }
}

The same issue with different usage:

namespace EcAnalytic\Tables;

class QueryBuilder implements IQueryBuilder {

    protected function buildQuery() {
        $this->exprToCol = new \SplObjectStorage();
        $this->joins = new \SplObjectStorage();
    }
}

I get this in xml report:

      <DependsUpon>
        <Package></Package>
      </DependsUpon>

instead of <Package>+spl</Package> in other cases (like a package in gobal namespace annotated with @Package).

The way I checked it was by modifying PDepend\Metrics\Analyzer\DependencyAnalyzer::visitMethod() like this:

public function visitMethod(ASTMethod $method)
    {
        $this->fireStartMethod($method);

        $namespace = $method->getParent()->getNamespace();
        foreach ($method->getDependencies() as $dependency) {
            if ($dependency->getNamespace()->getName() == '')) {
                echo "DEP: ".$namespace->getName().'\\'.$method->getParent()->getName().'::'.$method->getName().PHP_EOL;
                echo " -> ".$dependency->getNamespace()->getName().'::'.$dependency->getName().PHP_EOL;
            }
            $this->collectDependencies($namespace, $dependency->getNamespace());
        }

        $this->fireEndMethod($method);
    }

This is what I get nowadays with PHP Depend 2.13.0 for both code examples above:
