[Php56] Skip multiple catch with same variable on AddDefaultValueForUndefinedVariableRector

[samsonasik]

Given the following code:

class SkipMultipleCatchWithUseSameVariable
{
    public function run()
    {
        try {
        } catch (\Exception $e) {
            var_dump($e);
        } catch (\Throwable $e) {
            var_dump($e);
        }
    }
}

It cause result:

     public function run()
     {
+        $e = null;

which should be skipped.
