If we expect m_userMediaPermissionRequestManager to be NULL some of the time, do we really want an ASSERT here?

By design, when nulling m_userMediaPermissionRequestManager, we set back the capture state to none. For the capture state to be different from None, m_userMediaPermissionRequestManager should in theory be recreated.

So we do not expect it to be null but we cannot ignore the fact that a wrong IPC message may happen.
