Title: Video: Fix volume cookie.

Volume cookie is fixed in this PR ([BLD-518](https://edx-wiki.atlassian.net/browse/BLD-518)).

When the user changes the volume for the currently playing video, a cookie is stored in the browser which remembers the volume specified by the user. For next video played, this setting should be remembered.

@valera-rozuvan please review.
