Sidenav - .mat-sidenav-opened is not being applied after switching mode from side to over #6062
Description
Bug, feature request, or proposal:
Bug
What is the expected behavior?
Class mat-sidenav-opened should be added to <md-sidenav-container> in mode over (or perhaps for all modes?).
What is the current behavior?
The class is not being added if the component was initialized with side mode and then switched to over.
What are the steps to reproduce?
Providing a Plunker (or similar) is the best way to get the team to see your issue.

What is the use-case or motivation for changing an existing behavior?
When changing size of the screen (e.g. rotating device) it is useful to change mode between side and over. Class mat-sidenav-opened is also useful as it tells when side-nav is closed and animation completed.
