General
Each tasks can be cancelled and that shall be visible in the final print out in the service overview.

Expected result

• the Tasks contains now the cancellation fee (in the pricing section)
  
  
• if the task was cancelled the statement with the cancellation fee is still in place, but istead of rendering the initial price for the service we render the cancelation fee . f.e Task price is 100 Euro and cancelation fee is 60 Euro, if the task is in any state other then "cancelled" cancelled we render price 100 Euro if in cancelled - 60 euro
  
  
• since the SERVICE price is calculated out of the all tasks prices this would effect the service price
  f.e. there are 3 tasks earch is 100 Euro with cancellation fee of 50 Euro. 2 got completed and one cancelled the final price of the service is to be 100+100+50=250 Euro.
  
  
• in the export where we export the completed services we need to make sure we incude a new column "cancellation fee", amount of cancelled task in the service
