Updating a task now sends only data that's actually needed (Fixes #7846) (#8040)

* 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

* Changes according to review (use _.omit)
