Public Schedule: Expanded session info - add position and organization, hide top profile icon and details on top when expanded

[mariobehling]

Some information is repeated in expanded sessions. The website generator hides some info on expanding sessions. Please implement something similar on the frontend. Compare http://2019.fossasia.org/event/schedule.html

Make changes as follows:

• When session is expanded hide profile image, name, designation and org on the top area
• Leave session info on top area as is
• On the expanded area show position and organization below the speaker name without brackets
