Transform2D Tests

- Transform2D: eventListener wasn't being added for parentComponent
REMOVED_FROM_PARENT if the parentComponent was already added to the
scene (this is why cleanUpParentTransform wasn't erroring in coded
tests)
- C2D_Tests_Transform_00: tests a scene being created immediately
- C2D_Tests_Transform_01: tests a scene being created over time and
demonstrates the error where transforms aren't being inherited (press
space to update the scene)
