ConcreteInheritance behavior

[cristianoc72]

At line https://github.com/propelorm/Propel3/blob/master/src/Propel/Generator/Behavior/ConcreteInheritance/Component/PreSave.php#L77 if I try to persist dependencies, this test https://github.com/propelorm/Propel3/blob/master/tests/Propel/Tests/Generator/Behavior/ConcreteInheritance/ConcreteInheritanceBehaviorTest.php#L109 causes an infinite loop.

If I don't persist dependencies, this test https://github.com/propelorm/Propel3/blob/master/tests/Propel/Tests/Generator/Behavior/ConcreteInheritance/ConcreteInheritanceBehaviorTest.php#L169 causes the following error:

There was 1 error:

1) Propel\Tests\Generator\Behavior\ConcreteInheritanceBehaviorTest::testPreSaveCopyData
Exception: Dependency not found. From Propel\Tests\Bookstore\Behavior\ConcreteContent to Propel\Tests\Bookstore\Behavior\ConcreteCategory. Did you forget to persist() it?
