Subtasks lose their indent when switching columns

[FearTheBadger]

Moving items to any new column, messes with the hierarchy of the task.

if I have:

• [ ] This is a parent task #Later
  • [ ] This is a sub #Later

and I move This is a sub to #Soonish, I get the following

• [ ] This is a parent task #Later
• [ ] This is a sub #Soonish
