* Updating a task now sends only data that's actually needed (Fixes#7846)
Updating a task with a huge history lead to 'request entity too large' errors since the client attempted to send all data associated with a task, regardless of whether that data could be changed or not. With this change, the post request is now omitting the following fields:
challenge
completed
createdAt
group
history
id
reminders
tags
type
updatedAt
userId
