Assemble: ignore devices= if container= is present.
If "container=" is present, then we are going to assemble from the
given container where that container is made of those devices or not.
So in this case the "devices=" is purely documentation and is best
ignored.
As part of this, move the test on the "container=" value when that
start with "/" up before the device is opened. There sooner we test
things, the better.
