Title: Nested `change:attr` events do not fire in 0.9.0

Given a model with two `change:attr` callbacks, if the first is invoked, and then kicks off some logic that should trigger the second, the second will not be invoked, because the model's `alreadyChanging` var is already truthy. The attached test fails in 0.9.0 but succeeds in 0.5.3.
