Reason for canceled session not appropiate on adding new session

[Daniel Kulesz]

When adding a new session, there is the checkbox and field to enter information about why this session was canceled. Both options are greyed out but obsolete, in case you add a new session since you would probably never want to add a new, canceled session.

The way the elements are styled imposes, that after clicking "canceled" you could enter the information, but the checkbox is disabled anyways.

Suggested fix: Completely hide both the checkbox and the field when adding new sessions.
