fix(LargeVideoManager): frozen displayname in a msg

The "data-i18n-options" attribute value is stored in jQuery cache and
at the time when i18-next tries to access it to do the translation
it gets the old value from the cache and the message is not updated
correctly. Passing the "msgOptions" explicitly to "translateElement"
fixes the problem by avoiding jQuery cache.
