Fix SI-5971.

When using `AbstractTransformed` abstract inner class in views in order
to force generating bridges, one must take care to push the corresponding
collection trait (such as `Iterable` or `Seq`) as far as possible to the
left in the linearization order -- otherwise, overridden methods from these
traits can override the already overridden methods in view. This was the
case with `takeWhile`.
