 Record filters fail when the property being accessed has a value of NULL.


 {{{
 class Foo extends Doctrine_Record
 {
   public function setTableDefinition()
   {
     $this->hasColumn('a', 'string');
   }

   public function setUp()
   {
     $this->unshiftFilter(new FooFilter());
   }
 }

 class FooFilter extends Doctrine_Record_Filter
 {
   public function filterGet(Doctrine_Record $record, $name)
   {
     if($name == 'b')
     {
       return NULL;
     }
   }
 }

 $foo = new Foo();
 var_dump($foo->b);

 Expected:
 NULL

 Actual:
 Doctrine_Record_Exception is thrown because property/relation "b" doesn't
 exist on Foo
 }}}

 I've traced the problem to line 980 in the Doctrine_Record class file:
 if (($value = $filter->filterGet($this, $fieldName, $value)) !== null)
