Issue/Introduction

When you are trying to create tasks through Rest API where we first created the level 1 task P1 and when you are attempting to create 3 sub tasks under it in the order C1, C2, C3, the tasks are getting created in the order C3, C1, C2.

STEPS TO REPRODUCE: 

1. Create project in Clarity
2. Create Task in the project called Level 1
3. Attempt to create tasks through Rest API under level 1 task
