bug(sidenav): the drawer-container is animated when initialized

Bug, feature request, or proposal:

Bug

What is the expected behavior?

When initializing a md-sidenav-container, the container should not be animated.

What is the current behavior?

When initializing a md-sidenav-container, the container is animated.
The md-sidenav (alias md-drawer) is initialized, the open-instant animation state is used, opening the sidenav without animation.
However there is no such thing on the md-drawer-container: the transition is always set.

What are the steps to reproduce?

_{No time for a plunkr yet but I will provide it later if necessary}

What is the use-case or motivation for changing an existing behavior?

Since the drawer is not animating, it makes no sense to animate the container.
_{And since the drawer is being initialized, (open)/(close) events are not triggered}

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

beta-10

Is there anything else we should know?
