Valera/fix empty captions panel no captions

Fixed 2 failing Jasmine tests. Removed unnecessary console.log() call.
Initializing of variables in a single var statement.

Now the captions panel will be shown with captions only after successful

"There is a white panel over a non-youtube video."
When the captions file is not specified, we simply do not render the captions panel.

methods in wsgi.py and manage.py for both projects.

Comments (and processing instructions!) are handled oddly in lxml.
This change will keep them from causing failures.  They will be omitted
from the HTML generated, which is fine, since they aren't needed there.
